ABSTRACT:
An improved annular cutting disc of the type having an inner annular edge as the cutting edge. The disc is comprised of a thin, metallic core member upon which a coating which is a slurry of nickel and diamond particles is plated and is the cutting coating. The coating extends radially inwardly from the inner wall of the core member towards the axis of the annular cutting disc to provide the cutting edge thereof. The cutting edge of the coating has a greater axial extent than the axial extent of the coating of the radial outward extent thereof. The coating defines a pair of axially extending shoulders at the radial outward extent upon which a coolant may impinge to reduce deleterious thermal effects. If desired, a first coating of nickel may be plated intermediate the cutting coating and the core member.
