Remark

There are horseshoe and oblique chipways designs;
To drill media hard, hard and crack not grown formation with rock hardness not above f15 and in place where the compacting power of the rock drill doesn’t exceed 8Kg/MPa

To drill hard, very hard and crack grown formation

There are short skirt, average long skirt and enhanced long skirt;
with hemi-spherical or parabolic inserts configurations;
to drill all rock formations except very hard and abrasive formations

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.
