We introduced Opti-Cut cutting teeth from Backer Hughes,and each cutter had the optimal geometry, so that no matter how the cutting teeth are arranged on the cutting or milling tools, the blade edge or tip is facing up. When the teeth wear out, new blades and tips will appear. The new cutting teeth have a total of 16 blade tips and 8 blade edges. Applications range from tubing fishing, packer milling, sleeve milling, casing/pipe cutting, and milling to wherever extremely sharp cutting edges are required.
