The tool features a small angle of inclination of the helical profile, which effectively prevents lifting and vibrations of the machined material. It performs excellently in precise cutting, welding, and edge levelling of thin materials with a thickness from 1 mm to 8 mm on CNC machines and overhead spindle milling machines. The finishing geometry with one edge (Z1) combined with a polished chip groove prevents sticking and melting of the material. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system and ensuring stability during machining.\u003c\/p\u003e\u003ch3\u003eDesign 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 flexible sheets.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSingle-edged Z1 (positive) design:\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 groove:\u003c\/strong\u003e The mirror finish of the spiral prevents sticking and re-welding of chips to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing geometry of the blade:\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 shank surface prevents slipping in the holder and protects the spindle cone from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing in class G2.5:\u003c\/strong\u003e Balancing in accordance with ISO standards ensures vibration-free operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003ePurpose and application range:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for cutting operations and edge welding and levelling in thin plastic sheets on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed in the processing of materials such as: PLEXI (acrylic), plastics, ALUCOBOND® panels, ALUCOBOND® A2, and composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444636885332,"sku":"ST28.03.012.060.03R","price":15.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.03.012.060.03R_198.03.012.060.03RPS-108.jpg?v=1791281481","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d3-i12-l60-s3-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
