general purpose wheel choice for light to medium stock removal. Typical
applications include surface grinding, tool and cutter grinding, and
drill sharpening.
Works well on tool steels (hardened, forged and stainless) and cast iron
General purpose wheel for light to medium stock removal
NORPOR Wheels – High porosity for heat-sensitive applications
NORPOR 25A — Pink, friable aluminum oxide abrasive with VP2 porous bond are designed to grind a broad variety of heat-sensitive steels at light to moderate feed rates
Controlled porosity bond for increased chip clearance and maximum coolant flow, reduced loading, and cool cutting - wet or dry - in heat sensitive applications
Durable bond post for maximum grain retention
Less dressing; longer wheel life
Maximum depth of cut for increased grain efficiency; consistent grinding action at high metal removal rates
