The tool is equipped with a small helix angle, effectively preventing lifting and vibrations of the machined material. It performs excellently for precision cutting as well as for edge jointing and aligning thin materials ranging from 1 mm to 8 mm thick on CNC machines and router milling machines. The finishing geometry with a single blade (Z1) combined with the polished chip flute prevents sticking and melting of the chips. The ground shank in H6 accuracy class 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 flimsy sheets.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSingle-blade design Z1 (positive):\u003c\/strong\u003e The single cutting edge allows for efficient chip removal, minimizing friction and the risk of overheating the material.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flute:\u003c\/strong\u003e The mirror surface of the spiral prevents sticking and secondary welding of the chips to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing blade geometry:\u003c\/strong\u003e Precisely sharpened edge guarantees perfect edge quality without fraying.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The 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 ensures 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 cutting operations, as well as for edge jointing and aligning in thin sheets of plastic on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, and composites such as CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444833067348,"sku":"ST28.03.012.060.06R","price":26.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.03.012.060.06R_198.03.012.060.06RPS-107.jpg?v=1794297828","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d3-i12-l60-s6-rh-acabado-positivo-1","provider":"ITA TOOLS","version":"1.0","type":"link"}
