The tool features a three-flute spiral geometry with a roughing profile in positive \u003cstrong\u003eZ3\u003c\/strong\u003e configuration, which ensures effective chip removal upwards and a clean finish on the bottom edge of the workpiece. The dedicated roughing teeth efficiently break the workpiece into smaller particles, reducing cutting resistance and relieving the machine's drive system. The ground shank with a tolerance class of \u003cstrong\u003eH6\u003c\/strong\u003e eliminates radial runout, protecting the spindle and guaranteeing a high level of stability during operation.\u003c\/p\u003e\u003ch3\u003eStructural advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eZ3 roughing design (upward chip removal):\u003c\/strong\u003e Three cutting edges with a roughing profile reduce working resistance, efficiently remove chips upwards, and allow for machining at high feed rates while maintaining a clean bottom edge.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePremium solid carbide (VHM):\u003c\/strong\u003e The rigid monolithic design limits tool deflection under load and ensures high dimensional precision.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePossibility of PVD coating application:\u003c\/strong\u003e The option of applying protective coatings (including 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 shank:\u003c\/strong\u003e The shank surface with a roughness indicator of \u003cstrong\u003eRa ≤ 0.3 µm\u003c\/strong\u003e prevents the mill from rotating in the holder and eliminates the risk of wearing out 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 a stringent class \u003cstrong\u003eG2.5\u003c\/strong\u003e (according to ISO\/EN) reduces noise and diminishes vibrations generated at high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eApplication and range of use:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for cutting, preliminary shaping, and efficient rough machining operations.\u003c\/p\u003e\u003cp\u003eIt performs exceptionally well in the machining of materials such as: soft and hard wood, plywood, as well as raw particle board and raw MDF board.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445037277524,"sku":"SF01.20.072.120.20R","price":223.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SF01.20.072.120.20R_195.20.072.120.20R-108.jpg?v=1791283239","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-desbaste-vhm-z3-d20-i72-l120-s20-rh-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
