Our tapered button bit was from high quality cemented carbide and produced with heat treatment technology,which connected with
tapered drill rod well for air leg or hand-held rock drill machine for drilling holes in gold and coal mining,marble and granite
quarries,stone project, tunnel, water conservancy,etc.

What is the advantage of our tapered drill button bit ?
1. Material: 100% virgin raw material with submicron grain size;
2. Grade: Various grades for choice;
3. Advanced production equipments and testing equipments
4. Precision Ground and polished;
5. High wear resistance,high hardness and impact toughness;
6. Samples & small orders are acceptable.

Bit face shape selection:China high air pressure mining button 152mm hard rock dth hammer water well drill bits
1. Drop Center Bit For high penetration rates in soft to medium hard and corrosive rock formations. Low to medium air pressures.Maximum hole deviation control.
2. Concave Face
The all-round application bit face specifically for medium hard and homo generous rock formations. Good hole deviation control and good flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
5. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures.Good penetration rates an resistance to steel wash.

     
  

We need to confirm the following Product Specification before placing an order:

1. The type of drill bit;
2. The head diameter of drill bit;
3. Bit face shape Choice: (Main shapes are:

Thread Button Bits 
Thread button drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized thread button drill bits according to different drilling application, and custom drill bits are applicable to drill soft rock, loose-medium rock and hard rock.
