Designed for efficient rough machining, deep cutting and forming of dies and 3D models in aluminium, plastics and composites. The chip breaker reduces the machined material into smaller pieces, which limits cutting resistance, reduces vibrations and prevents chip evacuation channels from clogging. The narrowed body eliminates the risk of the gripping part rubbing against the material walls during deep penetration. The right-hand spiral efficiently removes the workpiece from the bottom of the cut, ensuring a clean working environment. The ground shank in H6 tolerance guarantees axial precision and protects the CNC machine spindle.\u003c\/p\u003e\u003ch3\u003eDesign advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eUndercut design (neck):\u003c\/strong\u003e The narrowed body prevents collisions with the material during deep milling, facilitates chip removal and reduces friction.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eRoughing geometry with chip breaker:\u003c\/strong\u003e The profiled blades break down the workpiece into fine particles, reducing cutting resistance and preventing chip jamming.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eThree-flute design (Z3):\u003c\/strong\u003e Three cutting edges provide a high level of rigidity, enabling operation at higher feed speeds.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eUpward chip evacuation (positive):\u003c\/strong\u003e The right-hand chip channel lifts dust and chips, protecting the bottom of the cut and the underside of the material from damage.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip grooves:\u003c\/strong\u003e The smooth surface of the spiral reduces friction and counteracts aluminium sticking to the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid carbide (VHM):\u003c\/strong\u003e The rigid structure dampens vibrations and ensures a long lifespan when machining with large allowances.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow roughness of the shank (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground shank prevents slipping in the holder and protects the spindle taper from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing G2.5:\u003c\/strong\u003e Compliance with ISO standards ensures safe and smooth operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003ePurpose and range of application:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for rough cutting, deep carving, joining and preliminary shaping of 3D models on CNC machines.\u003c\/p\u003e\u003cp\u003eUsed in processing materials such as: aluminium, plastics and composite boards like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444894048596,"sku":"SR34.16.040.150.16R","price":131.4,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SR34.16.040.150.16R_195.16.040.150.16RM-107.jpg?v=1791282616","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-con-cuello-para-relieves-3d-vhm-z3-d16-i40-l150-s16-rh-desbaste-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
