Description

Tungsten Carbide Button Drill Bit , Diamond Drill Bit for Drilling Granite

Introduction of PDC:

Polycrystalline Diamond Compact(PDC), is manufactured with a diamond layer attached to a

carbide substrate. Combining the properties of both super hardness and abrasion resistance

of diamond with outstanding strength and toughness of tungsten carbide, PDC has been

widely used in mechanical industry,oil well drilling,geological prospecting drilling and coal mining.

It possess of high wear resistance like diamond, at the same time the impact resistance like hard

alloy and that’s made it the best material as a drill bit cutter. Reinforced PDC has higher dense

diamond powder, claw hard alloy substrate made the two layers solid as whole one. So,

there-inforced PDC of supper wear resistance, longer service life and high efficiency.

Description of coal mine rock drill bit:

PDC anchor shank bit is the most basic part of roadway support in coal mines. It can bound the

surrounding rock of roadway together, and make the surrounding rock to support itself. Roofbolt

drill bit is a kind of drilling tool for fixing anchor bolt of coal mine. The two wings of our PDC

roofbolt drill bit adopt PDC (Polycrystalline Diamond Compact) as the cutting tooth, the application

of PDC has greatly improved the drilling efficiency of roofbolt drill bit, and is taking the place of tungsten

carbide roofbolt drill bit gradually.

Features of coal mine rock drill bit:

1. The cutting tools adopts new type superhard material;shelf life of drill bit is high.

2. Drilling efficiency of medium hard and harder stratum can be greatly improved.

3. Cutting edge is wearable, no need of polishing, easy to operate.

Application of coal mine rock drill bit:

Anchor-shank drill bit with PDC cutter is mainly applied to the anchor network support hole drilling in

underground coal mine, transportation,water conservancy and hydrpower,etc.
