3-Flute Design with Exhaust Groove : Engineered for significantly reduced noise and vibration during plunge cutting, ensuring a smoother operation and extended machine life.
Flat Bottom & Controlled Depth : Produces a clean, flat-bottomed pin chamber, preventing the key from sticking or becoming irremovable even if cut-through occurs (e.g., on “BuYang” type through-hole keys). Eliminates secondary finishing — one-pass perfection.
Optimized Geometry Data : Cutting profile is precision-calibrated based on extensive measurement of high-lift difference keys (e.g., 6-pin high-lift difference keys), ensuring the most accurate biting translation and fit.
Premium Material : Made of Tungsten Carbide (Carbide) for exceptional wear resistance and durability.
