This end mill is purpose-built for detailed metalworking tasks where clean slots and precise shoulders matter. The two‑flute design strikes a practical balance between material removal and surface finish, while the 30° helix helps manage cutting forces and chip flow during longer cuts. The Weldon shank and flatted portion ensure stable, secure engagement with your collets or chucks, reducing runout and improving repeatability. Ideal for shops needing a versatile, durable tool for slotting and shoulder operations in common steel applications.
