These specifications translate into tangible benefits: the 7 mm cutting diameter is precise for narrow slots and accurate shoulders, while the 33 mm length of cut enables deep milling without re‑positioning. The 8 mm plain shank fits common collets and holders, reducing setup time. The HSS‑E cobalt construction maintains hardness at higher speeds, extending tool life on tough materials. The 30° helix supports smooth chip evacuation and a clean finish, and the 12° rake angle helps reduce cutting forces during shoulder and slot milling. Suitable for free‑machining steel and copper alloys, it’s a dependable choice for production runs that demand consistent results and fewer tool changes.
