About products and suppliers:

Rock drill bits are a kind of tool that is used to drill through rocks, concrete, and bricks. It is recommended to use rock drill bits with the rotary hammer drill. When operating, the hammer drill hammers the bit into rocks, then the surface of the rocks breaks into fragments. Continuously move the hammer drill and make a new action. Keep in mind to make sure the hammer drill is compatible with the mining drill bits so that the hammer will not damage the rock bits during operation.

Material of rock drill bits

There are various materials that can be used to make rock drill bits, such as tungsten carbide and diamond. Rock drill bits made of tungsten carbide are stronger and more durable than that made of other materials. They are tough enough to withstand grinding away at the stone with an abrasive. Tungsten carbide rock drill bits are suitable for all kinds of small holes. As for rock drill bits made of diamond, there is a diamond coating covering the surface of the drill bit, which makes them ideal for drilling into granite rock and drilling bigger holes.

Types of rock drill bits

When it comes to rock drill bit types, there are star drill bits, diamond drill bits for rock, pneumatic rock drill bits, and more. Star drill bits have several blades joining to the middle, just like a star. They're used as hand power drills, plus hammers to drill holes in the stones. Pneumatic rock drill bits use compressed air to power the hammer to make the movements hitting the rocks while drilling. Some diamond drill bits for rock with a diamond tip grind well into very hard rocks. They are the right choice for drilling into limestone and granite rocks. Some limestone drill bits come with a set of different drill bits and stand-by drill shank adapters. It's convenient to replace the drill bits for different rocks, making them multifunctional and affordable. Moreover, how to choose the rock drill bits types depends on the texture, hardness, and size of the rocks to be drilled.
