Designed for precise cutting, edge bonding, flattening, trenching, and grooving in plexiglass, plastics, and composites on CNC machines and overhead milling machines. The left-hand screw line presses the workpiece against the table and removes chips downwards, which is ideal for machining small parts and flexible plastic sheets. The special finishing geometry with one blade (Z1) combined with a polished chip flute effectively prevents material sticking and melting, ensuring a perfectly finished upper surface edge. The ground shank in the accuracy class 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-blade design Z1 (negative):\u003c\/strong\u003e The single cutting blade efficiently removes chips downwards, stabilising the material on the operating table.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flute:\u003c\/strong\u003e The mirror-like surface of the spiral counteracts chip sticking and re-welding with the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing blade geometry:\u003c\/strong\u003e The precisely ground edge ensures perfect edge quality without fraying and damage to the upper surface.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eMonolithic sintered carbide (VHM):\u003c\/strong\u003e The 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 The ground shank surface protects the holder and spindle cone from wear and prevents slippage.\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\u003ePurpose and range of application:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for cutting, edge bonding, flattening, trenching, and grooving operations in plastics on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed for machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® panels, ALUCOBOND® A2, and composites like CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445025841492,"sku":"ST51.03.012.060.06R","price":26.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST51.03.012.060.06R_198.03.012.060.06RPN-107.jpg?v=1791283167","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-vhm-z1-d3-i12-l60-s6-rh-acabado-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
