The tool is equipped with a small helix angle, effectively preventing lifting and vibrations of the machined material. It performs excellently in precision cutting, edge joining, and alignment of thin materials with a thickness of 1 mm to 8 mm on CNC machines and overhead spindle 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 the 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 for 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-edged Z1 design (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 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 edge 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 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 in accordance with 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, edge joining, and alignment in thin plastic sheets on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for processing materials such as: PLEXI (acrylic), plastics, ALUCOBOND® panels, ALUCOBOND® A2, and composites such as CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445148688724,"sku":"ST28.04.008.060.04R","price":18.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.04.008.060.04R_198.04.008.060.04RPS-107.jpg?v=1794297895","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d4-i8-l60-s4-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
