The four‑flute design provides a solid balance between material removal and finishing capability, helping maintain stable cuts even on longer reach operations. TiCN coating reduces wear and heat build‑up, enabling higher cutting speeds and improved tool life when milling tougher alloys. The 30° helix and 12° rake angle optimize chip formation and shoulder integrity, reducing rubbing and providing cleaner shoulders and slots. With a Weldon‑type 16 mm shank, it clamps securely in standard tool holders, ensuring repeatable performance across jobs that require dependable accuracy and surface finish.
