Here is 12 inch cutting wheel for metal, it is made of high quality aluminum oxide grains, used for cutting angle bar, T bar, flat bar, pipe etc. Due to super thin, it has fast cutting while have excellent durability feature.

The 12 inch cutting wheel is T41 flat shape with 25.4mm ring, single net.

Question: Factors affecting the durability of cutting discs

1. The cross-sectional area of the workpiece to be cut is too large. When cutting, the contact surface of the grinding wheel and the workpiece is too large to generate more high temperature. The resin in the carbonized grinding wheel causes the bonding force and the holding force to decrease; the cross-sectional area of the workpiece is too large and the material is too hard. The grinding wheel with softer hardness should be selected; the cross-sectional area of the workpiece is too small and the material is general, and the grinding wheel with harder hardness should be selected;

2. The material of the workpiece to be cut is relatively hard. During cutting, the friction between the grinding wheel and the workpiece generates more resin in the high-temperature carbonized grinding wheel, which leads to a decrease in the bonding force and the holding force; the improvement is the same as above a;

3. The hardness of the grinding wheel is harder or softer, and the harder grinding wheel is basically the same as above; the softer grinding wheel has insufficient holding force, and the abrasive material is impacted by the workpiece after the grinding wheel contacts the workpiece under high-speed rotation.
