Thread Button Bit
HOW TO CHOOSE A STYLE
Normal drill bit
Suitable for ordinary rock, hardness 8-14, abrasive rock. The main appearance is flat type, tooth diameter is moderate, alloy impact resistance and wear resistance balance, multi-choice high-ball teeth and semi-ballistic teeth, generally adapted to a variety of rocks, for the general rock and unclear rock type of the case are recommended.
Soft rock drill bit
Mainly applicable to non-breaking, hardness of 8 or less, non-abrasive rock. The main appearance is concave, tooth diameter is small, alloy impact resistance and wear resistance is better, more selection of semi-ballistic teeth, ballistic teeth, powder intensifying effect is better than ordinary type, in order to improve work efficiency.
Hard rock drill bit
Mainly used in F14 and above, non-abrasive rocks. The main performance is a large profile, tooth-shaped multi-choice ball teeth and high-ball teeth, alloy wear resistance, and impact resistance are better, powder ginger effect is slightly lower than an ordinary drill bit. Because the amount of alloy is more, the price is higher than that of the normal type.
Retrac drill bit

Hemispherical button
The tooth height is low, mainly used in extremely hard rock F14 or above, improves wear resistance, prevents the appearance of broken teeth, and the speed is lower.

BIT FACE SHAPE SELECTION
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.
Concave face
The all-around application bit face is specifically for medium hard and homogeneous rock formations. Good hole deviation control and good Flushing capacity.
Convex face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistant to steel wash. And may reduce the Load and wear on the gauge buttons, but poor hole Deviation control.
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.
Flat face bit
