Spiral Insert Heads

Our spiral insert knife cutter heads make constant contact with the surface of the material in a helical pattern offering reduced cutting noise - typically 20 decibels less. Each long wearing carbide knife has four edges that can be dulled before replacement. These moulder cutter heads improve material finishes on wood cross grain, lower long term tooling cost, and eliminate sharpening costs. Our molder spiral heads offer special radius edge inserts to reduce any chance of knife corners marking your material. Made from 7071-T6 high strength aircraft aluminum the cutter head is both strong and easy to handle. Heads include a set of carbide knives ready to run and a torx wrench for turning and replacing the knives. Our heads use 15 x 15 x 2.5 - 8 radius insert knives.
