The tool features a three-flute spiral geometry in a \u003cstrong\u003eZ3R\u003c\/strong\u003e configuration with a positive arrangement, ensuring immediate removal of dust and chips upwards and maintaining perfect cleanliness of the lower edge. The blade breaker significantly reduces the mechanical loads on the system and crushes the cut material, enabling operation at higher feed rates without loss of stability. The ground shank with a tolerance class of \u003cstrong\u003eH6\u003c\/strong\u003e eliminates radial runout, protecting the spindle bearing system and ensuring impeccable detail quality.\u003c\/p\u003e\u003ch3\u003eDesign advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eChip breaker Z3R geometry (upward ejection):\u003c\/strong\u003e The arrangement of three cutting edges with a chip breaker reduces work resistance, streamlines the ejection of crushed material, and allows for fast feeding with ideal finishing of the lower edge.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePremium solid carbide (VHM):\u003c\/strong\u003e The rigid, monolithic construction prevents deformation of the end mill under high force, allowing for precision cutting maintenance.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePossibility of applying PVD coating:\u003c\/strong\u003e The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of the edge's lifespan, reduces friction, and protects against overheating.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow roughness of the shank:\u003c\/strong\u003e The shank surface with a roughness index of \u003cstrong\u003eRa ≤ 0.3 µm\u003c\/strong\u003e prevents the mill from rotating in the holder and eliminates the risk of wear on the spindle cone.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing to G2.5 standard:\u003c\/strong\u003e Certified static-dynamic balancing in the high-performance class \u003cstrong\u003eG2.5\u003c\/strong\u003e (according to ISO\/EN) reduces noise and vibrations generated at high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIntended use and scope of application:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for cutting operations, contour milling, pocketing, and semi-finishing and finishing machining.\u003c\/p\u003e\u003cp\u003eIt works excellently with materials such as soft and hard wood, raw MDF board, plywood, and raw particle board.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444875338068,"sku":"SC03.12.042.090.12R","price":78.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SC03.12.042.090.12R_SC03.12.042.090.12R-104.jpg?v=1791282491","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-acabado-vhm-z3-d12-i42-l90-s12-rh-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
