Dedicated to demanding cutting operations and efficient removal of large material excess in aluminium, plastics, and composites. The specially profiled cutting edge grinds the material into smaller pieces, which reduces cutting resistance, prevents clogging of channels, and reduces spindle load. The arrangement of three cutting edges combined with a right-hand helical design ensures higher tool rigidity and efficiently removes chips from the underside of the material. The ground shank with H6 accuracy class eliminates radial runout, protecting the machine drive system.\u003c\/p\u003e\u003ch3\u003eStructural advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eRough machining geometry with chip breaker:\u003c\/strong\u003e The profiled teeth crush the chip into smaller parts, reducing cutting resistance and preventing material 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 chip upwards, protecting the lower edge of the workpiece from damage.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flutes:\u003c\/strong\u003e The mirror surface of the spiral reduces friction and prevents material 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 ensures durability when working with large excesses.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow grip 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 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\u003eIntended use and application range:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for rough cutting, splitting, 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":57445190992212,"sku":"SR33.25.035.080.20R","price":170.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SR33.25.035.080.20R_SR33.25.035.080.20R-110.jpg?v=1793968454","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-aluminio-y-plasticos-vhm-z3-d25-i35-l80-s20-rh-desbaste-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
