Generally the 14 grit, 30 grit, 70 grit and 120 grit are the frequently used grit sizes on metal bond diamond tooling throughout the grinding process.
When come to the bond types, it depends on the concrete hardness, if the floor is hard, the metal bond should be softer, in opposite the metal bond should be harder.
After choosing the diamond tooling ,it is necessary to check diamond tooling after a pass or two to determine if the concrete is too soft causing excessive wear or if the concrete is too hard and it’s not grinding much at all
