Description
Inquiry

Taper button bit as small hole bit is different with thread button bit as it use taper match bit with rod to be used for air leg or hand

held jack hammer driller in quarrying and mining. 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 normally

used. Taper angles of 11° and 12° are normally used on modern drill rigs.

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

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.
