Designed for efficient rough machining, cutting, and slotting on CNC machining centres and overhead spindle milling machines. The left-hand helical flute (negative) presses the material against the work table, eliminating the risk of tear-out on the upper edge of the workpiece. Three spiral blades with a profiled chip breaker reduce cutting resistance, lower spindle load, and effectively dampen vibrations during intensive cutting. 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-fluted roughing design Z3 (negative):\u003c\/strong\u003e Dedicated rough 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 bending of the tool 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 operation.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eOptimised grip roughness:\u003c\/strong\u003e The surface of the shank features low roughness (Ra ≤ 0.3 µm), preventing slippage in the holder and protecting the spindle taper from wear.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic balancing class G2.5:\u003c\/strong\u003e Static-dynamic balancing according to ISO\/EN standard (class G2.5) eliminates vibrations at maximum rotational speeds.\u003c\/li\u003e\u003c\/ul\u003e","brand":"ITA TOOLS","offers":[{"title":"Default Title","offer_id":57444807835988,"sku":"SF51.10.042.090.10R","price":53.4,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SF51.10.042.090.10R_196.10.042.090.10R-105.jpg?v=1793968266","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-desbaste-vhm-z3-d10-i42-l90-s10-rh-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
