The tool is equipped with counter-rotating helical cutting edges that simultaneously push the chips down from the top edge and up from the bottom, pressing the laminate against the core of the board. Designed for finishing machining, cutting, edge banding, and nesting technology cutting on CNC machining centres. The compression design eliminates the risk of chipping and tearing on both sides of the machined material. The ground shank in the H6 accuracy class eliminates radial runout, ensuring smooth machining and a long spindle life.\u003c\/p\u003e\u003ch3\u003eConstruction advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eCompression geometry (Positive-Negative):\u003c\/strong\u003e The combination of right-hand and left-hand cutting edges guarantees a smooth, clean edge without chipping on both the upper and lower surfaces of the board.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing cutting edge geometry:\u003c\/strong\u003e Precisely sharpened cutting edges ensure high surface quality without the need for additional finishing processing.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid sintered carbide (VHM):\u003c\/strong\u003e The rigid monolithic construction reduces tool deflection under load and maintains dimensional precision.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground surface of the shank prevents slipping in the tool holder and protects the spindle taper from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing to class G2.5:\u003c\/strong\u003e Balancing in accordance with ISO standards eliminates vibrations at high rotational speeds.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSpecial protective coating TiSiN:\u003c\/strong\u003e A copper-coloured PVD coating, 1–4 µm thick, with high microhardness of 3570 HV (HV 0.05).
