Designed for precise cutting, edge bonding and alignment, grooving, and trenching in plexiglass, plastics, and composites on CNC machines and overhead milling machines. The left-hand helical flutes grip the workpiece to the table and evacuate chips downwards, making it ideal for machining small parts and flexible sheets of material. Special finishing geometry with a single edge (Z1) combined with a polished flute effectively prevents adhesion and melting of the material, ensuring a perfectly finished upper surface edge. The ground shank with H6 accuracy class 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-edged design Z1 (negative):\u003c\/strong\u003e The single cutting edge efficiently evacuates chips downwards, stabilising the material on the working table.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished flute:\u003c\/strong\u003e The mirror-like surface of the flute counteracts material adhesion and secondary welding of chips 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 carbide (VHM):\u003c\/strong\u003e High structural rigidity of VHM eliminates vibrations and allows for dimensional stability.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e Ground surface of the shank protects the holder and spindle taper from wear and prevents slippage.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing class G2.5:\u003c\/strong\u003e Balancing compliant 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 intended for cutting, edge bonding and alignment, grooving, and trenching operations in plastics on CNC machining centres.\u003c\/p\u003e\u003cp\u003eIt is used for machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, and composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444913840468,"sku":"ST51.03.006.060.06R","price":26.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST51.03.006.060.06R_198.03.006.060.06RPN-110.jpg?v=1791282735","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-vhm-z1-d3-i6-l57-s6-rh-acabado-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
