The configuration of two cutting edges (Z2) with a full radius on the ends allows for precise shape milling, sculpting, engraving, and machining of curved surfaces in 3D without leaving sharp edges. The right-hand spiral effectively lifts the chips upwards, preventing their accumulation in the cutting zone. Dedicated to finishing, cutting, and joining work on aluminium, plastics, and composite materials on CNC machining centres and overhead spindle milling machines. The finishing geometry combined with polished flutes prevents chip adherence to the cutter body. Ground shank with accuracy class H6 eliminates radial runout, protecting the machine's drive system.\u003c\/p\u003e\u003ch3\u003eStructural advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eBall nose geometry:\u003c\/strong\u003e Full radius on the tool ends enables precise 3D modelling, milling of spatial surfaces, and smooth transitions in internal radii.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eTwo-flute Z2 construction (positive):\u003c\/strong\u003e Two cutting edges increase the rigidity of the cutter 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 Right-hand spiral lifts the chips upwards, protecting the lower machined surface from scratches by chips.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished flutes:\u003c\/strong\u003e The mirror-like surface of the spiral reduces friction and effectively counteracts chip adherence to the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid carbide (VHM):\u003c\/strong\u003e The rigid and wear-resistant structure of the solid reduces vibrations and guarantees dimensional stability in precision details.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground surface of the shank secures against 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 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 intended for 3D finishing machining, sculpting, engraving, cutting, and joining 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":57445168054612,"sku":"SQ31.16.381.889.16R","price":90.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SQ31.16.381.889.16R_SQ31.16.381.898.16R-111.jpg?v=1791283955","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-de-punta-esferica-para-aluminio-y-plasticos-vhm-z2-d15-86-i38-1-l88-9-s15-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
