How to use diamond core drills, drill glass, ceramic, porcelain, wall tile, tile, limestone, marble, slate, granite, stone, tiles and fiberglass

Material hardness and abrasiveness

The materials have different degrees of hardness and abrasiveness. In addition, some natural and synthetic materials can vary significantly depending on the exact physical composition. For example, glass will vary depending on the hardness of color and type, such as various metals and minerals are added to the performance of different types and colors. Glass also different degrees of "temperament" in accordance with specific manufacturing methods used. ceramic tile, ceramic, porcelain and ceramics are of different types of glass and a vitrified material. They also have different hardness and abrasiveness as the type, composition, production and manufacturing methods used.

The hardness and abrasiveness of natural materials like stone, vary according to type, but also vary considerably from one specific type. Most stones are not pure – which are mixtures of different types of rocks. Granite for example, contains mainly various combinations of quartz, feldspar, black mica and amphibole. Therefore, a specific type stone like granite or marble, can vary significantly in hardness and abrasiveness as a function of the mineral composition varies depending on the exact location extraction.

Here is a picture of the hardness of different materials. The matrix uses the standard scale of Knoop hardness (kg/mm2). The more material Diamond is the hardest known, measuring Knoop 7000. tungsten carbide, carbide drill bits used is the hardest natural material after diamond. However, with a As of 2100, tungsten carbide is only 30% harder than diamond.

Speed drilling

diamond drill speeds vary by manufacturer and type of diamond drilling. Blunt nose Glasto Wireless designed to be used in the glass can be used to speed up to 10,000. But Diamond Core Bits for use on glass, stone and tiles must be used to stop a very slow rate, the rate decreases as the hardness and abrasiveness of the material increases. Moreover, as the circumference of only the increase the cutter diameter is larger, the system speed drill bit should be reduced to offset the large increase in the rate at which the outer edge of the cup is moving.

The following table shows the recommended drilling speeds for diamond core drills. Drill speeds significantly higher than these speeds quickly burn diamond pieces. Reduced speed of drilling, drilling low pressure and water use for lubrication to prolong life of the drill.

SPEED KILLS:

reduced speeds drilling low-pressure drilling and increased use of water lubrication of the bit to extend the life considerably.

As all materials vary in hardness and abrasiveness, is impossible to determine the exact speed drill. In addition, as we shall see, drilling lubrication and pressure should be taken into account in determining the correct speed drill. Enhanced speed drilling or increased pressure may reduce the cutting time slightly, but significantly increases the friction and heat until the wick reduce life dramatically and increasing the risk of fractures of lower heat and broken equipment. If used correctly, a bit boring diamonds should never be hot to touch after use. If you develop a bit of yellow, brown, blue or black "burn marks" around the tip is an indication of the extreme temperatures and speed drill used is too fast or the amount of pressure on the drill is too large.

Lubrication

The water or coolant should always be used to cool and lubricate the tip. Lubrication reduces heat buildup, prolonging the life of the bit and prevents fractures in the heat in the material. Water is most often used as a lubricant, because it works very well and has no cost. oil-based lubricants do not work well on small pieces of drilling glitter.

good lubrication is essential. Minimal lubrication keep the burn little, but very good lubrication techniques will extend a bit by a factor of 5 or even 10.

When drilling in fiberglass, a diamond drill can be used dry or with a very small amount of water. When drilling glass or ceramic tiles, pottery and porcelain, and lubricated, dust the cut must be dissipated in the water. Contact with surface drilling should is always a little wet and should never be hot. If the tip is more than warm, usually an indication of lubrication a little (or maybe too much speed or pressure).

For drilling in hard and abrasive materials such as limestone, sandstone, ceramic and hard porcelain, marble or granite is essential to have a lot of lubrication. With these hard materials, it is common for drilling under water or a small amount of water constantly running during exercise and the hole. In both cases, the "pumping" technique described below is necessary to ensure the water reaches the end of the wick.

This discussion is presented as a guide only. It is almost impossible to have "too much" lubrication and the risk down is the mess of water being shaken by the bit. However, "too little" lubrication cause many problems.

Lubrication Tips and Techniques

The different types of highly specialized equipment for industrial water supply are available for the work of industrial-type production. But when is drilled with diamond cuts, the main concern is just to get enough water for lubrication in the forefront of the match, regardless of method used.

However, all lubrication methods are not equal. For proper lubrication to extend the life of the bit much, different methods to help people understand the differences between the different methods. In general, the relative ranking also gives a general indication of the forest life relation to different methods of lubrication. For example, the clay dam lubricating method (8 reviews) should make life a little bit about 4 times higher than using a dropper bottle (2 comments).

The most basic method is to use a small tube with water flowing on the surface near the hole and down into the well. For ensure proper lubrication on a horizontal surface, one trick is to place a plastic container or bottle with a small hole in the bottom of it, to the well. Drain water from the bottle and provides continuous lubrication as you drill. To allow lubrication to reach the tip of the bit, is important to use a "pump" technique described below. Without the technique of pumping, water rarely reaches the tip of the drill.

Another technique is an excellent lubrication to build a dam "around the well with a small amount of clay or similar material. This method is very effective, especially if the water spreads hole on the oil out of place for flushing the tip with good lubrication. "Pumping" the exercise will also increase lubrication the tip. The clay can be used several times if stored in a plastic bag, zip-lock style sandwich "to prevent drying.

For low volume repetitive work, it is also possible to place the material in a short cake "style of the pan (place a thin plastic panel at the bottom to avoid drilling into pan) and fill the pot with water so it covers the surface of the material being drilled. If possible, water should cover the oil hole in the side edge of the diamond drill.

When drilling on vertical surfaces, the only way to apply the water is to use a certain type of pipe. If this is not possible, a very effective solution is to have someone constantly "press" water in the well using a syringe. sprinklers tend to keep the burn little, but unless a pumping action is used, water rarely reaches the tip of the drill.

Whichever method of lubrication, using a periodic "pumping" action will improve significantly the lubrication on the tip of the drill. Due to pressure on the tip of the bit, the water is difficult to reach the wick. A "pump" technique allows lubrication to reach the final. While drilling, increase drilling up and down a fraction of an inch from time to time as you drill (Maybe every 20-30 seconds). This ensures that water gets inside the wick completely comprehensive and lubricates Council

Pressure Drilling

When using normal locks materials such as wood, the increased pressure causes the bit faster and has little effect on the friction or the accumulation heat into the tool. To enter Harder materials such as hardwood, is more important to reduce the pressure and let the song "Drilling at their own pace. "Otherwise, friction quickly lit fuse. When using diamond drill bits, the effect is similar to hardwood drilling but they are compounded because of the extreme hardness and abrasiveness of the material being drilled.

When using diamond drill glass, ceramic or porcelain, stone limestone, marble and granite, etc, is very important to have only the light of the average pressure in the drilling and to allow the piece of drilling at their own pace. increase the pressure does not significantly accelerate the cut, but will increase significantly and the friction cause rapid overheating of the drill. This not only wick burns, but also warms the surrounding surface and heat can cause fractures or breaks occur.

If you develop a bit of yellow, brown, blue or black "burn marks" around the tip, is an indication that extreme heat caused by excessive drilling speed or too much pressure on the bit. Impact Type "Percussion drills" should never be used with diamond drills, as offer no benefit and will end the drill fungi or separation.

If a hole is drilled completely through a piece of material, also is important to "alleviate" considerable pressure when the fuse is located near the rear of the field. This reduces breakages and fractures in the back the material when the bit is clear from the rear

Balancing cutting speed, drilling speed, pressure and lubrication

The cutting speed and life of a diamond drill affected by the hardness and abrasiveness of the material so that the drill speed, pressure and lubrication. Experience with specific hardware allows a person to quickly determine the optimum drilling speed, pressure and lubrication of the fastest cutting at least some impact on life and the risk of fracture or break from the heat. However, when experience fails, it is best to start with a very slow speed drill, very low pressure and a lot of lubrication. This point reduces the minimal risk and extends the life that is considerably

Pilot drill

bit drivers are often the standard metal core bits and hole saws designed for use in wood and other soft materials. Only one pilot a small hole in the center of the hollow core drilling, which keeps everything in focus from only one hole. bit drivers are particularly useful when using a drilling base with a hand drill. Since some drivers are not present, a lock cylinder may tend to "walk" to it settles into the slot.

However, the pilot bits are rarely used on pieces of core diamond drilling, as there are many disadvantages of a driver with little diamond logo drilling and drilling in hard materials.

A small diamond driver adds a significant cost to already expensive bits diamond drill core.
Diamond is often before the driver of small main gear.
drilling time can be considerable when drilling very hard materials and a pilot bit drilling time increased further.
A few pilot removes water from oil hole supply shaft and not use the core team of water supply.

A model can be used to run a basic exercise that has a little rider. This simple technique is discussed in the next section.

From a core drilling through a model

Core bits over 1 / 2 "are more effective when used in an exercise column instead of a hand drill. Home of some base when using a drill press is simple, because it keeps the drill bit moves. To reduce bit slippage or "run" when using a hand drill, a model can be done to help start the forest, if necessary.

A model is made by drilling a hole in a piece of wood or soft plastic, using the diamond drill bit base or through a cut in "V" on the edge of a piece of wood or plastic or a hole the size of core drilling. The working model of hole better, however, the "V" model is easier to do and can be used with many sizes of core drilling.

Models often 1 / 8 "plexiglass, 1 / 8" of plywood or cardboard, even. For repetitive drilling, a plastic or plexiglass model works best as the water lubrication can be used immediately. The model is placed on the surface of the material being drilled with a hole or "V" on the surface of the target hole. The base model will hold the drill in place as it begins. After only a few laps of the wick, establishing a groove and the model can be removed.

Bore Depth

bonded diamond core drills are designed to drill to a depth of approximately 1 / 2 ". When drilling with holes in the population of 1 / 2 "thick (as a slab of marble or stone), it is generally preferable to drill to a depth of approximately 1 / 2" then carefully chip to the central 'plug' with a chisel or screwdriver to punch before continuing. This process reduces friction and heat buildup caused by the "cap" and reduce cutting time and increase the life of the wick.

When drilling holes of large diameter (2 cm in width and more) in some hard materials such as marble or granite, it is sometimes difficult to break the record without drilling small holes in the lid so you can be removed in sections.

Drill deep holes with bonded diamond drill bits is generally limited to about 1 inch deep, according to particular material being drilled. Even removing the core period, increasing friction and still considerable depth limits boring. For deeper holes, some sintering of diamond drilling is usually required. bits, the most expensive diamond sintered incorporated directly into the tip metal and are most suitable for deep drilling.

Ceramic tiles and porcelain

Although it is a clear advantage from the standpoint of wear, new ceramic tile is often difficult to drill without a bit of diamond drilling.

The porcelain was originally developed as an alternative to ceramic tiles for use in applications where the land use and the wear is extreme. Porcelain tiles made with different mixtures of materials, often including feldspar and quartz, which are two major components of natural granite resources. The use of porcelain tiles has generally been limited to commercial applications, but by the 1980s, the use of porcelain tiles increased more in residential construction.

In the 1990s, manufacturers of tiles began to expand their product lines in porcelain to include many different styles and numerous closely resemble natural stone. Due to the natural stone appearance, the use of porcelain tiles on walls and countertops have become more popular. Finally, late 1990 test tile manufacturer with new techniques of porcelain manufacture which made it much more difficult. Like ceramic tile, was a breakthrough that leads to reduced wear and long life. However, many porcelain tiles are now as hard as granite and some are even more difficult. The new type of high quality, "" Super-hard, "Class V porcelain stoneware: it is almost impossible to break more than the tip of the spear" carbide drill and generally can not be pierced with a diamond drill.

To drill the new super-hard tile with a diamond drill is the only reasonable option. However, even with a small diamond drilling, the drilling process is long and extremely hard material is not very forgiving if improper drilling techniques are used. It is essential that drilling techniques suitable for use. correct speed of drilling, drilling pressure low and good lubrication is essential.

Drilling Glass Block

The hole in the glass block is basically no different than drilling in the normal glass. If you keep a low speed drilling using low pressure and plenty of water for lubrication, you'll be fine. However, there are some facts very important tips that will help people in their task.

There are many types and styles of glass blocks made by many manufacturers. Most have some kind design, however, for drilling are two very important features to consider. glass block varies significantly in thickness of the wall glass and of course, is tempered glass. This information is not usually disclosed in the block itself, but should be considered in the acquisition of blocks of glass for crafts.

If drilling glass block was installed on a wall, has no choice but to drill what is there. However, for art projects, it's good be very selective. If the block of glass 3 / 8 inch thick will take three times more compared with perforation of the block with a 1 / 8 "thick wall. In addition, will triple by the drill wear, causing living under only one third the time.

Tempered glass is sometimes used in glass blocks to increase the bearing capacity of the block. Tempered glass has varying degrees of humor, and if it can be drilled should be avoided if reasonably possible glass block. may increase the wet drilling time from 200% to 500% or more compared with non-standard tempered glass. Also, depending on your mood, the little glass drill life can be reduced by 75% to almost 90%.

experienced craftsmen who work with glass blocks eventually learn to find different types and styles of blocks proof glass. After drilling a sample of each block, it clearly has a thin wall block that block is wet. In addition, the artisans who are drilling lots of glass blocks, usually develop some method of drilling stove, so that the block can be drilled under water to improve lubrication and extend the life of the drill. The dam of "clay" method of lubrication is also very effective for drilling in the block of glass. technical water lubrication are discussed in greater detail in the lubrication Tips & Tricks section.

glass block is normally a vacuum inside. Some of the water and glass powder always aspired to inside when drilling. But it is easy to rinse the inside of the block with water if the water is dirty let dry. The filler cap can be pulled into the block, but usually drop out easily when empty inside. However, if the pressure too much emphasis in the year that breaks the hole can cause the plug to have a talent for jumping in the back hole. Normally, you can remove the cap with a pair of needle nose pliers, but the best solution is to reduce the working pressure to avoid breaking the drill chips.

A final bit of glass block Tips

A piece of wire from a hanger regular work very well to insert it into the hole to "grow" lights throughout the interior of the block, so all the corners are of lights.

A hand drill works well using a basic model and a dike of clay – a few blocks of glass. However, a drill press is worth the cost cheaper if you do a lot of blocks. There are many very nice, cheap drill presses available these days and that Quick and easy drilling glass block a hand drill.

A 1 / 2 "diamond drill core functions is the right size and appears to be the most popular measure for drilling glass blocks. However, we prefer a 5 / 8 "bit, because the hole slightly gives a great little place during insertion of the lights, pushing her around or remove them easily if you change your mind (or the need to change a light bulb).

Finally, if you ever have the opportunity to test the LED "or" lights ", try them – especially the large chains of 60 or 100 (need a few more lights because they are so small). Yes, they cost more, but almost no create heat, and almost always seen as important – usually have a "special" random pattern flashing strobe lights and flashes and flares, etc. The special effect of light is really worth the extra cost.

Diamond Drill Life

The life of all types of forests affected the hardness and abrasiveness of the material being drilled, the thickness of the material, the faster the electric drill, the amount and pressure used the use of proper lubrication. The hardness and abrasiveness of the materials may vary considerably. Even materials that seem to have a similar degree of hardness and abrasiveness. Drilling speed of each individual, the pressure and amount of lubrication varies considerably. Therefore, it is almost impossible to estimate the life of a small diamond.

For example, the standard 1 / 8 "glass, a small diamond galvanized 3 / 4" can last 200-300 holes, or more, depending specific techniques and drilling of glass specific use. The larger bits tend to run half the time due to a slightly different type of action cutting. Drilling 1 / 4 "of glass is twice as thick, normally produce only half of the wells are in a little life, so the hardness glass and drilling techniques are the same. Tempered glass has varying degrees of humor, and reduce the life of the bit from 75% to over 90%, compared to standard glass.

Lubrication has a significant effect on the life of the forest. The use of a central water or feel the device lubricants for drilling under the water level of water through the oil hole near the edge gives better lubrication and better simulation of life. using a type of clay "dam" gives lubrication pretty good, but since water is usually less than lubrication hole near the tip, lubrication inside the bit is much more limited. Therefore, using a method of lubrication of prey often reduce the life of drilling from 25% to 40%. Finally, spray or splashing water in the few studies of lubrication, lubrication, but is very limited and bit of life can easily be reduced 40% to 60% compared to using a water bath.

In very hard and abrasive materials, as granite or later the "super-hard" porcelain tiles, some diamonds in slavery holes can produce 6 to 12 March / 8 "material. Evidence, however, the same piece can produce up to 20 holes or more, all according to the specific material, thickness and specific drilling techniques used. In some Under hard, class III tiles ranged from 40 to 60 holes or more. wall tile is usually less difficult (but not always). However, only about 1 / 8 " 3 / 16 inch thick, the results in the brick wall are usually two to three times more than drilling in the same material that is 3 / 8 inch thick while using the same drilling techniques.

These examples are based on extensive testing of various materials using the actual speeds drilling, drilling pressure in the head, and lubrication. The results were much less, using bad techniques of drilling and testing using extreme improper drilling techniques often resulted in a bit of "Burning Up
