Cutting wheels

Cutting wheels without steel plate are manufactured with identical material. Thin thickness and high precision, they are mainly used for grooving and cutting with high accuracy and slight cutting depth. There are two kinds of bond: Metal bond (M) and Resin bond (B).

Future: The grits are strongly held on;
The wheels have Good wear resistance, long life span and good shape maintenance.

Future: The resin bond cutting wheels can self-sharpen and cut sharply. The quality of surface can be improved due to the elastic resin bond.

Shape:  
1A8/1 type without water slot and1A8/2 type with water slot.

Cutting wheel with steel core

www.allsupertool.com

This kind of cutting wheel is compound of steel plate and work layer. The steel plate has high strength and high rigidity. They are generally used for deep cutting and grooving. 

There are two kinds of bond: Metal bond (M) and Resin bond (B).


Future: The grits are strongly held on;
             Good wear resistance, long life span and good shape maintenance.

Feature: These wheels can self-sharpen and cut sharply. The work quality can be improved due to the elastic resin bond.

Shape:  1A1/3、1A1R/4 type without water slot and1A1/5、
