Brazed rotary cutting tool, an insert for a brazed rotary cutting tool, and methods for manufacturing the same

A brazed rotary cutting tool, comprising:

• a tool body;
• and
• a plurality of inserts brazed to the tool body, wherein each insert comprises a wear layer and a carbide substrate, wherein the inserts form at least two cutting edges, wherein a portion of each cutting edge exhibits a profile substantially resembling a first wave form, and wherein the locations of first wave form peaks along the longitudinal length of each cutting edge are offset from one cutting edge to another, and further wherein each insert has a rake face profile substantially resembling a second wave form and the rake face profile of each insert further has a bowed profile adapted to compensate for braze-induced cutting edge warp, wherein the bowed rake face profile comprises pre-determined variations of rake face offset along the cutting edge such that the rake face offset is relatively larger for portions of the cutting edge that exhibit an increase in cutting-edge diameter due to brazing induced warp of the insert, and the rake face offset is relatively smaller for portions of the cutting edge that exhibit a decrease in cutting-edge diameter due to brazing induced warp of the insert.
