ressure Dth Bits

General Introduction

Bit Face Shape 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-around application bit face specifically for medium hard and homogeneous 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 theload and wear on the gauge buttons, but poor hole deviation control.

4. 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.

Carbide Button Shape Selection:

1. Semi-Ballistic Buttons

2. Ballistic Button

3. Spherical Button

4. Two-step Button
