The tool features a small incline angle of the helical flute, which effectively prevents lifting and vibrations of the machined material. It works excellently for precision cutting as well as for welding and levelling edges of thin materials with thicknesses from 1 mm to 8 mm on CNC machines and vertical milling machines. The finishing geometry with a single edge (Z1) combined with a polished chip flute prevents chip sticking and melting. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine drive system and ensuring machining stability.\u003c\/p\u003e\u003ch3\u003eConstruction Advantages and Technical Properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eDedicated to thin materials (1–8 mm):\u003c\/strong\u003e Reduced spiral eliminates upward pulling forces, preventing the lifting of flimsy sheets.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSingle-edge design Z1 (positive):\u003c\/strong\u003e The single cutting edge allows for efficient chip removal, minimising friction and the risk of overheating the material.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flute:\u003c\/strong\u003e The mirrored surface of the spiral prevents sticking and secondary welding of the chips to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing geometry of the edge:\u003c\/strong\u003e Precisely sharpened edge guarantees perfect edge quality without fraying.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow roughness of the shank (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground surface of the shank protects against slippage in the holder and safeguards 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\u003ePurpose and Area of Application:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for cutting operations as well as for welding and levelling edges in thin plastic sheets on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed in machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, and composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445215338836,"sku":"ST28.64.254.635.64R","price":32.2,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.64.254.635.64R_ST28.64.254.635.64-112.jpg?v=1791284228","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d6-35-i25-4-l63-5-s6-35-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
