Remark |
There are
horseshoe and oblique chipways designs; |
To drill hard, very hard and crack grown formation |
There are short
skirt, average long skirt and enhanced long skirt; |
Note: 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.
