Designed for precise cutting, edge jointing, and leveling, as well as grooving and slotting in plexiglass, plastics, and composites on CNC machines and vertical milling machines. The left-handed spiral line presses the workpiece to the table and directs the chips downwards, making it ideal for machining small parts and flexible plastic sheets. The special finishing geometry with a single edge (Z1) combined with a polished chip groove effectively prevents sticking and melting of the material, ensuring a perfectly finished upper edge. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.\u003c\/p\u003e\u003ch3\u003eStructural Advantages and Technical Properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSingle-Edge Z1 Design (Negative):\u003c\/strong\u003e The single cutting edge efficiently directs the 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 chip sticking and re-welding to the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing Blade Geometry:\u003c\/strong\u003e Precisely ground edge ensures perfect edge quality without fraying and damage to the upper surface.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eMonolith of Cemented 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 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 intended for cutting, edge jointing, and leveling operations, as well as grooving and slotting 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 such as CORIAN® and HPL.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445136073044,"sku":"ST51.05.015.060.05R","price":20.7,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST51.05.015.060.05R_198.05.015.060.05RPN-208.jpg?v=1791283787","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-vhm-z1-d5-i15-l60-s5-rh-acabado-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
