Steelmax HSS annular Cutter,
 
Steelmax HSS cutters utilize an M2Al (aluminum additive) formulation which increases cutter life due to better heat propagation characteristics and a less brittle character compared to other M2 formulations, such as those using a cobalt additive.  HSS cutters are most cost effective for mild steel applications and holes up to 2-3/8″ in diameter in material up to 2″ thick. HSS annular cutters can be re-sharpened to extend cutter life.
All Steelmax cutters ship with a pilot pin installed at no extra charge.*
Steelmax High Performance Cutting Fluid should be used with all annular cutters for optimal cutting performance and to extend cutter life.  Our High Performance Cutting Fluid is a water-based cutting fluid that is bio-degradable and does not require time-consuming cleanup prior to welding or assembling parts.
