Infinity Tools Extended Tenon Shaper Cutter Sets, 1-1/4" Bore

The Insert-Pro Shaper System is built for woodworkers who need durability, accuracy, and flexibility. Each cutter body is CNC-machined from strong aluminum and finished with a protective coating for long service life. The replaceable knives are made from high-quality C4 micro-grain carbide and ground to an exceptionally sharp, polished edge. Unlike many shaper cutters that limit you to narrow tenons, this system is engineered to cut a full 2"-wide tenon, providing the strength needed for thick interior or exterior doors. The top and bottom profiles cut at the same time to simplify setup, and the cutter heads accept five different door profiles for impressive versatility. With the ability to create both 1/4" and 5/8" thick, 2"-wide tenons, this system adapts easily to a wide range of door-building projects.
