The tool features a small helix angle, which effectively prevents lifting and vibration of the processed material. It performs excellently in precise cutting as well as edge joining and levelling of 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 flute prevents chip sticking and melting. The ground shank with H6 accuracy class eliminates radial runout, protecting the machine's drive system and ensuring processing stability.\u003c\/p\u003e\u003ch3\u003eConstruction 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-edged Z1 (positive) design:\u003c\/strong\u003e The single cutting edge enables efficient chip evacuation, minimising friction and the risk of overheating the material.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished flute:\u003c\/strong\u003e The mirror-like flute surface prevents sticking and the re-welding of 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 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 designed for cutting operations and edge joining and levelling in thin sheets of plastic on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed in the processing of materials such as: PLEXI (acrylic), plastics, ALUCOBOND® panels, ALUCOBOND® A2, and composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445214716244,"sku":"ST28.32.794.635.32R","price":15.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.32.794.635.32R_ST28.32.794.635.32R-112.jpg?v=1791284225","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d3-18-i7-9-l63-5-s3-17-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
