The tool is equipped with a small spiral line tilt, which effectively prevents lifting and vibrations of the machined material. It performs excellently in precision cutting as well as edge joining and aligning thin materials with thicknesses from 1 mm to 8 mm on CNC machines and overhead milling machines. The finishing geometry with a single cutting edge (Z1) combined with a polished fluted groove prevents sticking and melting of the material. The ground shank in precision 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 flimsy sheets.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSingle-edge Z1 (positive) design:\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 fluted groove:\u003c\/strong\u003e The mirror-like surface of the spiral prevents sticking and secondary welding of chips to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing geometry of the blade:\u003c\/strong\u003e Precisely ground edge ensures perfect edge quality without fraying.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow grip roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground surface of the shank 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\u003eIntended use and scope:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for cutting operations as well as edge joining and aligning edges in thin plastic sheets on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed in the machining of 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":57445071094100,"sku":"ST28.08.012.060.08R","price":31.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.08.012.060.08R_198.08.012.060.08RPS-109_484df188-6602-4090-9165-9535a68d8116.jpg?v=1794304676","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d8-i12-l60-s8-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
