S7 TROCHOIDAL 5-FLUTE CUTTERS SOLID MILLING CUTTERS INTRODUCTION SEE TOOL IN ACTION We have launched a new generation of solid carbide five-flute end mills, specifically for dynamic milling applications in general machining and die and mold. The S7 assortment covers a wide range of operations, including profiling, trochoidal slotting, semi-finishing and narrow pocketing in a variety of materials, including stainless steels and super-alloys. S770HB / S772HB FEATURES & BENEFITS • Suitable for profiling, trochoidal slotting, and semi- to provide a stable performance, reduce chipping finishing applications. and prolong tool life. • A five-flute design for increased feed rates up to • Unequal helix for chatter free machining and 25%, compared with four-flute tools. excellent surface finishing. • Positive rake angle for smooth cutting action in • AlCrN coating for thermal stability, reduced friction, stainless steel and super-alloys, reducing the risk of excellent wear resistance and prolonged durability. work-hardening. • Maximum productivity due to optimal metal removal • Small corner radius and a specific cutting edge design rate and reduced machining time.
