Designed for precise cutting, welding, and edge smoothing in plexiglass, plastics, and composites on CNC machines and overhead milling machines. The finishing geometry with one blade (Z1) combined with a polished chip flute effectively prevents material sticking and melting. The right-hand helical design efficiently evacuates chips upwards, protecting the cutting zone from overheating and ensuring a smooth edge without the need for additional polishing. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the machine's drive system.\u003c\/p\u003e\u003ch3\u003eDesign features and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSingle-blade design Z1 (positive):\u003c\/strong\u003e The single cutting edge allows for rapid chip evacuation, minimising friction and the risk of overheating the material.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flute:\u003c\/strong\u003e The mirrored surface of the spiral prevents sticking and the secondary welding of chips to the tool body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing blade geometry:\u003c\/strong\u003e Precisely sharpened edge ensures cleanliness and smoothness of the edge after cutting.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid carbide (VHM):\u003c\/strong\u003e The rigid VHM construction reduces vibrations and maintains dimensional precision.\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 taper from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balance class G2.5:\u003c\/strong\u003e Balancing in accordance with ISO standards ensures vibration-free operation at very high rotational speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003ePurpose and scope of use:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for cutting, welding, and edge smoothing operations in plastics at CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for machining 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":57445170774356,"sku":"ST01.12.042.090.12R","price":61.1,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST01.12.042.090.12R_ST01.12.042.090.12R-102.jpg?v=1794297911","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-vhm-z1-d12-i42-l90-s12-rh-acabado-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
