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 decreasing spindle load. The arrangement of the three cutting edges combined with the right-hand screw helix ensures higher tool rigidity and effectively removes chips from the bottom of 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 chip into small elements, reducing cutting resistance and preventing the clogging of machined material.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eThree-flute Z3 construction:\u003c\/strong\u003e Three cutting edges allow for increased feed speed while maintaining smooth operation and high rigidity of the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePositive geometry:\u003c\/strong\u003e The right-hand spiral lifts the chips upwards, protecting the underside of the machined material from damage.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip grooves:\u003c\/strong\u003e The mirrored surface of the spiral reduces friction and prevents chips from sticking to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSintered carbide monolith (VHM):\u003c\/strong\u003e The rigid and wear-resistant structure of the monolith guarantees 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 in accordance with ISO standards ensures vibration-free operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003ePurpose and range of application:\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 for machining materials such as: aluminium, plastics, and composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445132042580,"sku":"SR33.20.032.080.20R","price":110.2,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-aluminio-y-plasticos-vhm-z3-d20-i32-l80-s20-rh-desbaste-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
