The tool is equipped with a small angle of helix, which effectively prevents lifting and vibrations of the processed material. It is perfect for precise cutting, welding, and aligning edges of thin materials with thicknesses from 1 mm to 8 mm on CNC machines and overhead milling machines. The finishing geometry with a single 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\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 lifting of flexible sheets.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSingle-edged Z1 design (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 groove:\u003c\/strong\u003e The mirror 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 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 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 application range:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for cutting operations as well as welding and aligning edges in thin plastic sheets on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, and composite materials like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444629446996,"sku":"ST28.03.008.060.03R","price":15.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.03.008.060.03R_198.03.008.060.03RPS5903247148847-101.jpg?v=1791281446","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d3-i8-l60-s3-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
