General Introduction：

Acedrills offers various cutting structures design configurations, include chisel bits, cross bits and button bits, for an extensive and diverse selection. These designs can be used in a variety of rock formations for maximum productivity, high penetration rate and long service life.

Specification Overview:

　 Chisel Bits Cross Bits Button Bits
Taper Degree 7o 7o, 11o and 12o 7o, 11o and 12o
Bits Socket Diameter mm 23 23 22
inch 27/32 27/32 7/8
Bit Diameter mm 26 ~ 43 28 ~ 51 28 ~ 45
inch 1 1/32 ~ 1 45/64 1 7/64 ~ 2 1 7/64 ~ 1 25/32
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;

  1. Choose big and high carbide bits, when work with high impact rock drills, to improve anti-percussive capability of the inserts;
  2. 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;
  3. The taper degree of the bits must be the same as the taper rods that it is planned to work with.
