Promax 119-02014 End Mill 5/16 in 3 Flute Altin Carbide

Product Description

The PROMAX 119-02014 is a solid carbide roughing and finishing end mill designed for high-performance material removal and surface finishing in a single tool. It features a 5/16-inch diameter, 3 flutes, and a 0.02-inch corner radius on a corner radius end geometry. The AlTiN coating provides heat resistance and extended tool life in ferrous and hardened materials. With a 40-degree helix angle and micrograin carbide construction, this end mill delivers aggressive chip evacuation alongside a quality surface finish. It is suited for milling operations on machining centers, CNC mills, and manual mills where precision and durability are required.

This end mill is used in general-purpose and production milling applications across metalworking shops, tool rooms, and manufacturing facilities. The corner radius geometry reduces edge chipping and stress concentration at the cutting corner, making it appropriate for pocketing, slotting, and profiling operations in steel, stainless steel, cast iron, and similar materials. The single-end, straight-cylindrical shank fits standard collet chucks and end mill holders for quick changeover.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature performance and extended tool life
• 0.02-inch corner radius reduces edge stress and improves surface finish
• 40-degree helix angle promotes efficient chip evacuation
• Center-cutting design allows plunge entry
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as a standard-shank replacement or production end mill for use in CNC machining centers and manual mills accepting 5/16-inch straight-cylindrical shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or end mill holder and torque to the tool holder specification per the manufacturer guidelines. Verify runout with a dial indicator before beginning cuts to maximize tool life and surface finish quality.
