Designed for precise cutting, edge bonding and alignment, mortising and grooving in PLEXI, plastics, and composites on CNC machines and overhead spindle mills. The left-hand helical flute pushes the work material down to the table and removes chips downwards, which is ideal for machining small parts and flexible plastic sheets. The special finishing geometry with a single cutting edge (Z1) combined with a polished chip groove effectively prevents material sticking and melting, ensuring a perfectly finished edge on the upper surface. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the machine's drive system.\u003c\/p\u003e\u003ch3\u003eDesign advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSingle edge design Z1 (negative):\u003c\/strong\u003e The single cutting edge efficiently removes chips downwards, stabilising the material on the work table.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip groove:\u003c\/strong\u003e The mirror-like surface of the spiral counteracts sticking and secondary welding of chips to the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing edge geometry:\u003c\/strong\u003e Precisely ground edge ensures perfect edge quality without fraying or 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 maintains 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 slipping.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balance 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, edge bonding and alignment, mortising, and grooving operations in plastics on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, as well as composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444974920020,"sku":"ST51.04.012.060.04R","price":18.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST51.04.012.060.04R_198.06.022.060.06RPN-1.jpg?v=1791282996","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-vhm-z1-d4-i12-l60-s4-rh-acabado-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
