Designed for precise cutting, edging, and aligning edges, grooving, and grooving in plexiglass, plastics, and composites on CNC machines and vertical milling machines. The left-hand screw line presses the workpiece to the table and removes the 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 edge on the upper surface. The ground shank in 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-edged Z1 design (negative):\u003c\/strong\u003e The single cutting blade efficiently removes chips downwards, stabilising the material on the operational table.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePolished chip flute:\u003c\/strong\u003e The mirror surface of the spiral counteracts sticking and secondary welding of chips to the body.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFinishing blade geometry:\u003c\/strong\u003e Precisely sharpened 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 maintains dimensional stability.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow shank roughness (Ra ≤ 0.3 µm):\u003c\/strong\u003e The 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, edging, and aligning edges, grooving, and grooving in plastics on CNC machining centres.\u003c\/p\u003e\u003cp\u003eUsed 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":57444818846036,"sku":"ST51.04.008.060.04R","price":18.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/ST51.04.008.060.04R_ST51.04.008.060.04R-103.jpg?v=1791282172","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-para-plexiglas-y-plasticos-vhm-z1-d4-i8-l60-s4-rh-acabado-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
