Reduced Noise: The spiral design allows a few knives to cut at a time, significantly lowering noise levels during operation. Extended Lifespan: Made from sintered tungsten carbide, the 15x15x2.5mm inserts are over 10 times more durable than high-speed steel, with each insert offering four usable edges. Easy Maintenance: Precision-ground inserts with a tolerance of ±0.0004" (±0.01mm) are interchangeable and easy to rotate or replace in minutes—simply loosen the screw, rotate 90°, and tighten.
