Abstract
Textured indentations in the cutting surface of the core of a cutting tool are designed to accommodate a single layer of superabrasive grain. The superabrasive grain contained in these textured indentations is thereby oriented during metal bond brazing such that a cutting edge of the superabrasive grain is oriented outward from the plane of the cutting surface of the core. Enhanced bond life, cutting performance and tool life are achieved.
Claims15
An abrasive tool comprising:
- a) a core having at least one cutting surface;
- b) superabrasive grain having at least one flat surface;
- and
- c) a metal bond brazed to the cutting surface of the core and the superabrasive grain;
- wherein the cutting surface of the core has indentations forming a texture, the indentations forming a texture being sized to contain a single layer of superabrasive grain oriented such that any flat surface of the superabrasive grain is inclined at an angle of at least 15.degree. relative to the plane of the cutting surface.
