Diamond Drill Bits

The diamond drill bit is a specialize bit to be used for boring large holes in bricks, concrete and stones. The name diamond is related to the industrial diamond embedded on the metal surface of the bit to help it cut through the toughest of the materials.

There are many advantages of using the diamond bit over the masonry bit. The diamond bit handles the toughest tasks, especially with concrete, without a problem and at the end cuts clean holes which are a bit difficulty with the conventional masonry bits which are helpless against tough materials. Another obvious advantage over conventional masonry drills is the core bit's efficiency — since very little of the removed core must actually be abraded, the power and operator effort required to drill a very large hole is reduced enormously, and the capacity of a given portable drill greatly increased. Hence the diamond drill bit proves to be a wise choice over the masonry drill bit.

The small diamond drill bits are also conveniently used to bore clean and chip free holes in granite, marble and glass and that too at high speeds. The diamond bits can be very well used with or without water lubrication. Diamond core drill bits for use with portable drills are commonly available in diameters from 20 mm to 130 mm. The only limit on length of the cylinder, and thus depth of the hole, is the need to remove the bit from the hole to clear dust. 300 mm cylinder length is not uncommon, although shorter bits are usual.
