 Different rock formation and rock drills require different taper angles. When drilling with high impact hydraulic rock drills in medium-hard to hard and abrasive rock formation, a wide taper angles is nomally used. Taper angles of 11° and 12° are normally used on modern drill rigs. For low impact rock drills and softer rock formation, a narrow taper angle of 7° is used. A 7° can also be used if bit spinning is a problem when using 11° and 12° equipment.

Notes:

1. Special sizes may be available upon request;

 

2. Choose big and high carbide bits, when work with high impact rock drills, to improve anti-percussive capability of the inserts;


3. Work with soft formation, use extreme hard carbide inserts bits to get high penetration; while work with hard formation, use sub-hard carbide inserts bits to avoid inserts breaking; work with erosive formation, use anti-resistance alloy carbide inserts;


4. The taper degree of the bits must be the same as the taper rods that it is planned to work with.
