• Specially blended aluminum oxide abrasive for many surface grinding applications. • The porous vitrified bond increases chip clearance and maximizes coolant flow, reduces loading and is cool cutting in heat-sensitive applications. • For use in Cortland Bonus Grind chucks on surface grinding machines. • Good choice when a broad variety of parts are ground on one machine. • Consistent performance at an economical initial price. • Surface grinding segments are generally used to grind flat stock or flat surfaces within a workpiece. The segment moves over the workpiece in a flat plane or vice versa. Applications can vary from heavy, rapid stock removal to precision tolerance operations.
