Designed for efficient roughing, cutting, and grooving on CNC machining centres and gantry milling machines. The left-hand helical design (negative) presses the material against the worktable, eliminating the risk of tear-out on the upper edge of the workpiece. Three spiral flutes with a profiled chip breaker reduce cutting resistance, decrease spindle load and effectively dampen vibrations during intensive machining. The ground shank in accuracy class H6 protects the drive system and ensures high process stability.\u003c\/p\u003e\u003ch3\u003eKey technical parameters and properties:\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eThree-flute roughing design Z3 (negative):\u003c\/strong\u003e Dedicated roughing profile with downward chip removal presses the workpiece against the table and ensures a perfectly finished, clean upper edge.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePremium class solid carbide (VHM):\u003c\/strong\u003e Rigid monolithic construction minimizes tool deflection under load and guarantees high mechanical durability.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eGeometry with chip breaker:\u003c\/strong\u003e Divides the machined material into smaller pieces, reducing cutting resistance and stabilising the operation of the system.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eOptimised shank roughness:\u003c\/strong\u003e The shank surface features low roughness (Ra ≤ 0.3 µm), which prevents slipping in the holder and protects the spindle taper from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing in class G2.5:\u003c\/strong\u003e Static-dynamic balancing in accordance with ISO\/EN standards (class G2.5) eliminates vibrations at maximum rotational speeds.\u003c\/li\u003e\u003c\/ul\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444753703252,"sku":"SF51.16.055.110.16R","price":136.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SF51.16.055.110.16R_196.16.055.110.16R-104.jpg?v=1791281937","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-desbaste-vhm-z3-d16-i55-l110-s16-rh-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
