Designed for precise cutting, edging, and machining edges, grooves, and slots in plexiglass, plastics, and composites on CNC machines and overhead milling machines. The left-handed screw line presses the workpiece against the table and removes the chips downwards, making it ideal for machining small parts and flexible sheets of material. The specially designed finishing geometry with a single cutting edge (Z1) combined with a polished chip flute effectively prevents material sticking and melting, ensuring a perfectly finished upper surface edge. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.\u003c\/p\u003e\u003ch3\u003eConstruction advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSingle cutter design Z1 (negative):\u003c\/strong\u003e The single cutting edge efficiently removes chips downward, stabilising the material on the working table.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flute:\u003c\/strong\u003e The mirror-like surface of the spiral prevents chips from sticking and welding back to the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing cutter geometry:\u003c\/strong\u003e Precisely ground edge ensures perfect edge quality without fraying and damage on the upper surface.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSolid sintered carbide (VHM):\u003c\/strong\u003e High structural rigidity of VHM eliminates vibrations and maintains dimensional stability.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow grip roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The ground shank surface protects the holder and spindle cone from wear and prevents slipping.\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\u003eIntended use and application range:\u003c\/h3\u003e\u003cp\u003eThe tool is designed for cutting, edging, and machining edges, as well as grooving and slotting in plastics on CNC machining centres.\u003c\/p\u003e\u003cp\u003eSuitable for processing materials such as: PLEXI (acrylic), plastics, ALUCOBOND® plates, ALUCOBOND® A2, and composites such as CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445151867220,"sku":"ST51.03.006.060.06RE","price":26.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST51.03.006.060.06RE_ST51.03.006.060.06RE-112.jpg?v=1793968516","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-vhm-z1-d3-i6-l60-s6-rh-acabado-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
