Norton SGA is a blend of aluminium oxide & ceramic grain grinding wheel. The SGA has 10% ceramic content as opposed to the 30% concentration in the 3SG range.
SGA is a cheaper alternative and will still perform well on almost all materials to be ground. The ceramic content of the wheel is designed to cut hardened steels such as D2 with minimal wheel wear and heat generation.
- Harder and sharper than conventional abrasive grains for good cutting capabilities.
- very versatile for use on a wide range of steels.
- Suitable for low to medium powered machines.
