Product Desciption

Product Introduction

Sollroc's thread button drill bits are made by high quality alloy steel bar and tungsten carbide inserts. 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.

The thread button bits are widely used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc.

Bit Face Shape	Introduction
Drop Center Face	For high penetration rates in soft to medium hard and fissured rock formations, Low to medium air pressures. Maximum hole deviation control.
Concave Face	The all-round application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good fishing capacity.
Convex Face	For high penetration rates m soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash. And many reduce the load and wear on the gauge buttons. But poor hole deviation control.
Double Gauge Face	This kind 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.
Flat Face Bit	This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressure. Good penetration rates are resistance to steel wash.

Product advantage

1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption

2. Smooth performance and long service life

3. Low problem rate and easy to maintenance

4. Easy to depart bit from hammer

5. Interchangeable with DTH bit and drill pipe
