The tool features a small helix angle, which effectively prevents lifting and vibrations of the processed material. It is ideal for precise cutting, edge joining and levelling of thin materials with a thickness from 1 mm to 8 mm on CNC machines and vertical milling machines. The finishing geometry with a single cutting edge (Z1) combined with a polished chip flute prevents sticking and melting of the chips. The ground shank with H6 accuracy eliminates radial runout, protecting the machine's drive system and ensuring machining stability.\u003c\/p\u003e\u003ch3\u003eStructural 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-flute 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-like surface of the spiral prevents sticking and re-welding of the chips to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing geometry of the blade:\u003c\/strong\u003e Precisely ground 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 G2.5 class:\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 scope of application:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for cutting, edge joining, and levelling edges in thin plastic sheets on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed in the processing of materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, as well as composite materials like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445162844500,"sku":"ST28.64.127.635.64R","price":32.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.64.127.635.64R_ST28.64.127.635.64R-112.jpg?v=1791283931","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d6-35-i12-7-l63-5-s6-35-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
