Designed for demanding cutting operations and efficient removal of large material allowances in aluminium, plastics, and composites. The specially profiled cutting edge crushes the chips into smaller pieces, reducing cutting resistance, preventing clogging of the channels, and reducing spindle load. The arrangement of three cutting edges combined with a right-hand screw helix provides higher tool rigidity and effectively removes chips from underneath the material. The ground shank in H6 accuracy class eliminates radial runout, protecting the machine’s drive system.\u003c\/p\u003e\u003ch3\u003eDesign advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eRoughing geometry with chip breaker:\u003c\/strong\u003e The profiled teeth break the chips into small pieces, reducing cutting resistance and preventing the workpiece from jamming.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eThree-flute Z3 design:\u003c\/strong\u003e Three cutting edges allow for increased feed rates while maintaining smooth operation and high body rigidity.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePositive geometry:\u003c\/strong\u003e The right-hand spiral lifts the chips upward, protecting the lower edge of the work material from damage.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip grooves:\u003c\/strong\u003e The mirror-finish surface of the spiral reduces friction and prevents the chips from sticking to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid carbide (VHM):\u003c\/strong\u003e The rigid and wear-resistant structure of the solid material ensures durability when working with large allowances.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground surface of the shank prevents slipping in the holder and protects the spindle taper from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing in class G2.5:\u003c\/strong\u003e Balancing compliant with ISO standards guarantees vibration-free operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIntended use and application range:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for rough cutting, shaping, and welding operations in aluminium, plastics, and composite materials on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed in the machining of materials such as: aluminium, plastics, and composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445195776340,"sku":"SR33.20.060.120.20R","price":315.84,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SR33.20.060.120.20R_195.20.060.120.20RA-111.jpg?v=1791284094","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-aluminio-y-plasticos-vhm-z3-d20-i60-l120-s20-rh-desbaste-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
