The tool is equipped with a small helix angle, which effectively prevents lifting and vibrations of the processed material. It works perfectly for precise cutting as well as back-beveling and edge truing of thin materials with a thickness of 1 mm to 8 mm on CNC machines and spindle milling machines. The finishing geometry with a single cutting edge (Z1) combined with a polished chip groove prevents sticking and melting of the chips. 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\u003eConstruction advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eDedicated to thin materials (1–8 mm):\u003c\/strong\u003e Reduced helix eliminates upward pulling forces, preventing lifting of flimsy sheets.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSingle-edge Z1 (positive) design:\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 helix prevents sticking and re-welding of chips to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing blade geometry:\u003c\/strong\u003e Precisely ground edge ensures perfect edge quality without fraying.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e Ground shank surface 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 guarantees 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 back-beveling and edge truing of thin plastic sheets on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for machining 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":57445168283988,"sku":"ST28.05.008.060.05R","price":20.7,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST28.05.008.060.05R_198.05.008.060.05RPS-109_1c65a4ee-4329-4f4c-b1c4-ec3f488a77f9.jpg?v=1793969488","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-con-bajo-angulo-de-helice-vhm-z1-d5-i8-l60-s5-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
