Abstract: A contoured rake face cutting tool and method of making is disclosed. A rotary cutting tool with a plurality of teeth can cause damage to a work piece during cutting. By orienting the cutting angle of the teeth relative to the rotational central axis to high shear angle such as 50 or 70 degrees, the tool creates a high compression cut which is cleaner and less damaging to the work piece. The cutting surface itself is profiled, i.e. non-planar, such as concave or convex or other non planar shape, which is preferably formed into an ultra-hard material which is supplied for use in a planar form.

Abstract: A high shear angle cutting tool and method of making is disclosed. A rotary cutting tool with a plurality of teeth can cause damage to a work piece during cutting. By orienting the cutting angle of the teeth relative to the rotational central axis to 50 degrees or greater, the tool creates a high compression cut which is cleaner and less damaging to the work piece.
