The arrangement of two cutting edges (Z2) with a full radius on the tips allows for precise contour milling, sculpting, engraving, and machining of curved 3D surfaces without leaving sharp edges. The right-hand spiral effectively lifts the chips upwards, preventing their accumulation in the cutting zone. Designed for finishing, cutting, and welding works in aluminium, plastics, and composite materials on CNC machining centres and overhead spindle milling machines. The finishing geometry combined with polished chip grooves prevents the chip from sticking to the body of the tool. The ground shank in tolerance class H6 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\u003eBall nose geometry:\u003c\/strong\u003e Full radius on the tool tips enables precise 3D modelling, milling of spatial surfaces, and smooth transitions into internal radii.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eTwo-flute Z2 construction (positive):\u003c\/strong\u003e Two cutting edges enhance the rigidity of the mill and allow for efficient work with smooth guidance in the material.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePositive geometry (upward chip removal):\u003c\/strong\u003e The right-hand spiral lifts chips upwards, protecting the lower machined surface from scratches by chips.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip grooves:\u003c\/strong\u003e The mirror-like surface of the spiral reduces friction and effectively prevents chip adhesion to the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid carbide (VHM):\u003c\/strong\u003e The rigid and wear-resistant structure of the solid carbide reduces vibrations and guarantees dimensional stability with precise details.\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 chuck and protects the spindle taper from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing in class G2.5:\u003c\/strong\u003e Balancing according to ISO standards ensures vibration-free operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eApplication and usage range:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for 3D finishing machining, sculpting, engraving, cutting, and welding in aluminium and plastics 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":57445181325652,"sku":"SQ31.13.254.826.13R","price":51.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SQ31.13.254.826.13R_SQ31.13.254.826.13R-110.jpg?v=1791284038","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-de-punta-esferica-para-aluminio-y-plasticos-vhm-z2-d12-7-i25-4-l82-55-s12-7-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
