Designed for highly precise finishing machining of 3D, shaping deep reliefs and spatial surfaces in aluminium, plastics, and composites. The arrangement of three cutting edges combined with a right-hand screw thread provides high tool rigidity, vibration-free operation, and efficiently removes chips from the cutting bottom. Optimised design with an undercut (neck): The body constriction eliminates the risk of tool collision with the material during deep milling, facilitates free chip removal, and reduces friction, protecting the workpiece from overheating. The ground shank in accuracy class H6 eliminates radial runout, safeguarding the machine drive system.\u003c\/p\u003e\u003ch3\u003eKey technical parameters and properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eOptimised design with an undercut (neck):\u003c\/strong\u003e The body constriction eliminates the risk of tool collision with the material during deep milling, facilitates free chip removal, and reduces friction, protecting the workpiece from overheating.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing geometry:\u003c\/strong\u003e Precisely ground cutting edges allow for excellent surface quality without the need for additional finishing machining.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eThree-flute design Z3:\u003c\/strong\u003e Three cutting edges allow for an increase in feed speed while maintaining a smooth operation, excellent finish quality, and high tool rigidity.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePositive geometry:\u003c\/strong\u003e The right-hand spiral lifts the chips upward, protecting the lower edge of the material from scratching.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flutes:\u003c\/strong\u003e The mirror surface of the spiral reduces friction and prevents chips from sticking to the body of the tool.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePremium solid carbide monolith:\u003c\/strong\u003e The rigid and wear-resistant monolith structure guarantees long tool life and maintains tight dimensional tolerances.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eOptimised roughness of the shank:\u003c\/strong\u003e Low surface roughness of the shank (Ra ≤ 0.3 µm) prevents slippage in the holder and protects the spindle taper.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing in class G2.5:\u003c\/strong\u003e Static-dynamic balancing according to ISO\/EN standard (class G2.5) guarantees vibration-free operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eApplication and material purpose:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for finishing operations on 3D models, deep cutting, and grooving on CNC machining centres.\u003c\/p\u003e\u003cp\u003eMachined materials: Aluminium and composites such as CORIAN and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445104582996,"sku":"SR02.20.040.200.20R","price":493.35,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SR02.20.040.200.20R_193.20.040.200.20RM-210.jpg?v=1793968445","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-con-cuello-para-relieves-3d-vhm-z3-d20-i40-l200-s20-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
