• Applications: Shoulder milling, slot milling, and ramping in free-machining steel and copper alloys

This two-flute design delivers clean slots with efficient chip evacuation, helping to minimize chatter and achieve predictable tool life in tight pockets. The HSS‑E powder metallurgy construction offers enhanced wear resistance and edge retention, so you can rely on consistent performance across demanding jobs. With a compact form factor and neck relief, it maintains strong rigidity while reaching into confined areas, making it a practical choice for precision milling where space is limited. The 30° helix paired with a 12° rake angle supports smooth entry and consistent cutting in both steel and copper alloys, while the DIN 327 D shank standard ensures secure, repeatable mounting across compatible tooling systems.
