Designed for efficient rough machining, grooving, and slotting on CNC machining centres and overhead spindle milling machines. The left-hand spiral (negative) thread presses the material against the worktable, eliminating the risk of tearing on the upper edge of the workpiece. Three spiral blades with a profiled chip breaker reduce cutting resistance, decrease spindle load, and effectively dampen vibrations during intensive cutting. The ground shank with an accuracy class of H6 protects the drive system and ensures high stability of the process.\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 provides a perfectly finished, clean top edge.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePremium solid carbide (VHM):\u003c\/strong\u003e Rigid monolithic construction minimises 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), preventing slipping 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 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":57444894802260,"sku":"SF51.12.052.100.12R","price":76.6,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/4183\/0740\/files\/SF51.12.052.100.12R_SF51.12.052.100.12R-109_cce606eb-f70a-49a6-b213-674b8b8dc3aa.jpg?v=1793969474","url":"https:\/\/es.ita.tools\/en\/products\/fresa-helicoidal-desbaste-vhm-z3-d12-i52-l100-s12-rh-negativo","provider":"ITA TOOLS","version":"1.0","type":"link"}
