The arrangement of two cutting edges (Z2) with a full radius at the ends allows for precise contour milling, sculpting, engraving, and processing of curved surfaces in 3D without leaving sharp steps. The right-hand spiral effectively lifts the chips upwards, preventing their accumulation in the cutting zone. Designed for finishing, cutting, and welding operations in aluminium, plastics, and composite materials on CNC machining centres and overhead milling machines. The finishing geometry combined with polished chip flutes prevents the workpiece from sticking to the tool body. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the machine's drive system.\u003c\/p\u003e\u003ch3\u003eConstruction advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eBall nose geometry:\u003c\/strong\u003e Full radius at 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 design (positive):\u003c\/strong\u003e Two cutting edges increase the stiffness of the end mill and allow for efficient work with smooth guiding in the material.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePositive geometry (upward chip ejection):\u003c\/strong\u003e Right-hand spiral lifts chips upwards, protecting the lower machined surface from scratches by chips.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flutes:\u003c\/strong\u003e Mirror-like surface of the spiral reduces friction and effectively prevents chips from sticking to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid carbide (VHM):\u003c\/strong\u003e Rigid and wear-resistant monolithic structure reduces vibrations and guarantees dimensional stability with precision details.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e 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 according to ISO standards guarantees vibration-free operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIntended use and range of application:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for finishing 3D machining, sculpting, engraving, cutting, and welding in aluminium and plastics on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for processing materials such as: aluminium, plastics, and composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445167694164,"sku":"SQ31.48.159.635.48R","price":16.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SQ31.48.159.635.48R_SQ31.48.159.635.48R-111.jpg?v=1794297909","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-de-punta-esferica-para-aluminio-y-plasticos-vhm-z2-d4-76-i15-87-l63-5-s4-76-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
