The tool is equipped with a small helix angle, effectively preventing lifting and vibrations of the machined material. It is perfect for precise cutting, edging, and aligning the edges of thin materials with a thickness of 1 mm to 8 mm on CNC machines and overhead milling machines. The finishing geometry with one cutting edge (Z1) combined with a polished chip flute prevents adhesion and melting of the material. The ground shank with an accuracy class of H6 eliminates radial run-out, protecting the machine's drive system and ensuring machining 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 The reduced spiral eliminates upward pulling forces, preventing 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 flute:\u003c\/strong\u003e The mirror-like surface of the spiral prevents adhesion and secondary welding of chips with the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing edge geometry:\u003c\/strong\u003e The precisely sharpened edge ensures perfect edge quality without fraying.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground shank surface 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 guarantees vibration-free operation at very high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003ePurpose and Application Range:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for cutting operations as well as edging and aligning the edges of thin plastic sheets on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for processing materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, and composites such as CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444643864916,"sku":"ST28.04.012.060.06R","price":26.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.04.012.060.06R_198.04.012.060.06RPS-107.jpg?v=1791281498","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d4-i12-l60-s6-rh-acabado-positivo-1","provider":"ITA TOOLS","version":"1.0","type":"link"}
