1.Application for drill bits

Suitable for hole drilling or breaking the rock—Soft rock, loose-medium rock, hard rock and any other special formations, usually used in Stone/Quarry area, rocky area, and ore exploring. It is the first and important step to explore glod, silver,copper etc ore.

 

2.Material of the drill bits

Made with high quality of best quality alloy steel bar and tungsten carbides, 

 

through heat treatment so that it can withstand the toughest rock drilling demands,

 

and transmit intensive impact energy into the rock with the least possible loss of energy.

3.Type of the drill bits and Right selection

 

1. Drop Center Bit

 

For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control 

 

2, Concave Face

 

The all-round application bit face specially for medium hard and homogenerous 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.
