DRILLING AND SAWING ASSOCIATION

Abrasive Cutting

This is a basic method of forming a shallow cut into brick or concrete using an electric driven angle grinder. There are hydraulic and air driven machines, but the normal is 110 volt electric. These machines are fitted with either abrasive wheels or diamond tipped blades, usually running dry. Cutting is restricted to a depth of approx. 3.5" (85-90mm) as blades seldom exceed 225mm dia. (9"). These tools are efficient in brick and un-reinforced concrete but not very successful for cutting steel.
