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 upward and maintaining perfect cleanliness of the lower edge. The chip breaker applied significantly reduces the mechanical loads on the system and shreds the material, allowing for operation at increased feed rates without loss of stability. The ground shank in \u003cstrong\u003eH6\u003c\/strong\u003e tolerance class eliminates radial runout, protecting the bearing system of the spindle and ensuring impeccable detail quality.\u003c\/p\u003e\u003ch3\u003eDesign advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eChip breaker geometry Z3R (upward ejection):\u003c\/strong\u003e The configuration of three cutting edges with a chip breaker reduces work resistance, improves the ejection of shredded material, and enables fast feed with ideal finishing of the lower edge.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eMonolith made of premium sintered carbide (VHM):\u003c\/strong\u003e The rigid, monolithic structure prevents the deformation of the mill during operation under high forces, allowing for machining precision.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePossibility of applying PVD coating:\u003c\/strong\u003e The option of applying protective coatings (e.g., TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow roughness of the clamping part:\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 wearing the cone in the spindle.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing to G2.5 standard:\u003c\/strong\u003e Certified static-dynamic balancing in the high 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 application range:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for cutting operations, contour milling, grooving, and medium roughing and finishing machining.\u003c\/p\u003e\u003cp\u003eIt performs excellently in machining materials such as: soft and hard wood, raw MDF board, plywood, and raw chipboard.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445595709780,"sku":"SC03.18.055.110.18R","price":175.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SC03.18.055.110.18R_193.18.055.110.18RN-107.jpg?v=1793968205","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-acabado-vhm-z3-d18-i55-l110-s18-rh-positivo-1","provider":"ITA TOOLS","version":"1.0","type":"link"}
