The tool features a three-flute spiral geometry with a roughing profile in a \u003cstrong\u003eZ3\u003c\/strong\u003e configuration with a positive arrangement, ensuring effective chip removal upwards and a clean finish on the bottom edge of the workpiece. The dedicated roughing teeth effectively break down the material into smaller particles, reducing cutting resistance and relieving the machine's drive system. The ground shank in a tolerance class of \u003cstrong\u003eH6\u003c\/strong\u003e minimises radial runout, protecting the spindle and ensuring a high level of stability during operation.\u003c\/p\u003e\u003ch3\u003eStructural advantages and technical properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eZ3 roughing design (upward chip removal):\u003c\/strong\u003e Three cutting edges with a roughing profile reduce working resistance, efficiently remove chips upwards, and allow for machining at high feed rates while maintaining a clean bottom edge.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePremium solid carbide (VHM) construction:\u003c\/strong\u003e The rigid monolithic design limits tool deflection under load and ensures high dimensional precision.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePossibility of PVD coating application:\u003c\/strong\u003e The option to apply protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eLow roughness of the shank:\u003c\/strong\u003e The shank surface with a roughness indicator of \u003cstrong\u003eRa ≤ 0.3 µm\u003c\/strong\u003e prevents the end mill from rotating in the holder and eliminates the risk of cone wear in the spindle.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing to G2.5 standard:\u003c\/strong\u003e Certified static-dynamic balancing at a high class of \u003cstrong\u003eG2.5\u003c\/strong\u003e (according to ISO\/EN) reduces noise and vibrations generated at high speeds.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIntended use and application range:\u003c\/h3\u003e\u003cp\u003eThe tool is intended for cutting, preliminary shaping, and efficient rough machining operations.\u003c\/p\u003e\u003cp\u003eIt works perfectly in machining materials such as: soft and hard wood, plywood, and raw particle board and raw MDF board.\u003c\/p\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57445223072084,"sku":"SF01.12.042.090.12L","price":71.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SF01.12.042.090.12L_195.12.042.090.12L-102.jpg?v=1794297448","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-desbaste-vhm-z3-d12-i42-l90-s12-lh-positivo","provider":"ITA TOOLS","version":"1.0","type":"link"}
