The tool utilises three-edge spiral geometry in a \u003cstrong\u003eZ3\u003c\/strong\u003e configuration with a negative arrangement, which forces effective chip removal downwards. The use of high-quality micro-grain carbide provides high wear resistance and significantly extends the cutting edge's durability. The ground shank in tolerance class \u003cstrong\u003eH6\u003c\/strong\u003e eliminates radial runout, protecting the spindle bearing assembly and ensuring an excellent finish standard of the machined material.\u003c\/p\u003e\u003ch3\u003eConstruction advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eZ3 finishing geometry (downward chip removal):\u003c\/strong\u003e Three cutting edges directing the chips downwards guarantee a clean top edge of the raw material, prevent chipping, and effectively avoid lifting veneer or laminate at high feed speeds.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePremium sintered carbide monolith (VHM):\u003c\/strong\u003e The rigid, monolithic structure prevents deformation of the cutter during operation under high force, allowing for narrow dimensional tolerances to be maintained.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePVD coating option:\u003c\/strong\u003e The possibility of applying protective layers (e.g. TiSiN or PLATINIUM) allows for multiple extensions of the cutting edge's lifespan, reduces friction, and protects against overheating.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow roughness of the shank:\u003c\/strong\u003e The shaft surface with a roughness index of \u003cstrong\u003eRa ≤ 0.3 µm\u003c\/strong\u003e prevents the cutter from rotating in the holder and eliminates the risk of wear on the cone in the spindle.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing within G2.5 standard:\u003c\/strong\u003e Certified static-dynamic balancing in the stringent \u003cstrong\u003eG2.5\u003c\/strong\u003e class (according to ISO\/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIntended use and application range:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for cutting operations, peripheral milling, grooving, and edge finishing.\u003c\/p\u003e\u003cp\u003eIt works excellently for machining materials such as: soft and hard wood, raw and laminated MDF board, raw and laminated plywood, and raw and laminated particleboard.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445057954132,"sku":"SC51.20.060.120.20R","price":216.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SC51.20.060.120.20R_194.20.060.120.20R-204.jpg?v=1794302600","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-acabado-vhm-z3-d20-i60-l120-s20-rh-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
