The tool is equipped with opposite screw lines of the blades, which simultaneously push the chip down from the upper edge and up from the lower edge, pressing the laminate against the core of the board. Designed for finishing operations, cutting, jointing and edging, as well as 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 accuracy class H6 reduces radial runout, ensuring smooth machining and long spindle life.\u003c\/p\u003e\u003ch3\u003eStructural advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eCompression geometry (Positive-Negative):\u003c\/strong\u003e The combination of left and right twist blades guarantees a smooth, clean edge without chipping on both the upper and lower surfaces of the board.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing blade geometry:\u003c\/strong\u003e Precisely ground cutting edges ensure high surface quality without the need for additional finishing machining.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid carbide (VHM):\u003c\/strong\u003e The rigid monolithic construction reduces tool deflection under load and helps maintain dimensional accuracy.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground shank surface prevents slipping in the tool holder and protects the spindle cone from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing in class G2.5:\u003c\/strong\u003e Balancing in accordance with ISO standards eliminates vibration at high rotational speeds.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSpecialist protective TiSiN coating:\u003c\/strong\u003e Copper-coloured PVD coating, 1-4 µm thick, with a high microhardness of 3570 HV (HV 0.05).
