21 Aug 2018

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
Bits Socket Diameter	inch	27/32	27/32	7/8
Bit Diameter	mm	26 ~ 43	28 ~ 51	28 ~ 45
Bit Diameter	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;

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.

How to order?

Chisel Bit: Bit Diameter + Taper Degree + Socket Diameter + Head Design

Cross Bit: Bit Diameter + Taper Degree + Socket Diameter

Button Bit: Bit Diameter + Taper Degree + Socket Diameter + Skirt length + Insert Configurations
