Promax 122-03212 Ball End Mill 0.5 in 3 Flute Solid Carbide

Product Description

The PROMAX 122-03212 is a solid carbide ball end mill built for precision milling in demanding shop environments. It features a 0.5 inch cutting diameter, a 1.25 inch length of cut (LOC), and three right-hand flutes ground to a 35-degree helix angle. The ball-nose profile generates smooth, contoured surfaces in mold work, die cavities, and complex 3D tool paths. A TiCN coating increases surface hardness and reduces friction, extending tool life in ferrous and non-ferrous materials. This is a single-end tool from the PROMAX Series 122 line, designed for CNC machining centers and manual mills requiring consistent geometry and tight tolerances.

This ball end mill is suited for finishing and semi-finishing passes on contoured surfaces in tool-and-die, aerospace, and general precision machining applications. The 0.5 inch shank diameter provides rigid clamping in standard ER collets or end mill holders. The right-hand cutting direction and 35-degree helix promote efficient chip evacuation and reduce chatter during cut. It is a single-end tool, meaning once the cutting end is worn, the tool is replaced rather than indexed.

Key Features

• Ball-nose profile for contoured and 3D surface milling
• Solid carbide construction for rigidity and wear resistance
• TiCN coating for extended tool life in ferrous and non-ferrous materials
• 3-flute, right-hand geometry with 35-degree helix for efficient chip evacuation
• Single-end design from PROMAX Series 122
• 0.5 inch shank diameter fits standard collet and end mill holder systems

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 0.5 inch shank diameter end mill holder or ER collet system.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank to the full recommended grip length in the collet or holder and torque the retaining nut per the toolholder specification. Verify runout with a dial indicator before commencing a cut to avoid premature tool wear or breakage.
