Promax 120-03222 Roughing Finishing End Mill 1/2 in 4 Flute

Product Description

The PROMAX 120-03222 is a solid carbide roughing finishing end mill designed for material removal and surface finishing in a single tool. Built with 4 flutes and a 40-degree helix angle, it delivers efficient chip evacuation and smooth cutting performance across a range of ferrous and non-ferrous materials. The 0.02-inch corner radius reduces stress concentration at the cutting edge and minimizes workpiece chipping. A TiCN coating adds hardness and heat resistance to extend tool life under demanding cutting conditions. This end mill is suited for use by machinists and tooling professionals in job shops and production environments.

This end mill is configured for milling operations requiring a combination of stock removal and finish passes. The corner radius end geometry makes it appropriate for applications where sharp internal corners are not required and where edge durability is a priority. With a 1/2-inch shank diameter, it fits standard collet and end mill holder setups on vertical and horizontal machining centers as well as knee mills. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling operations.

Key Features

• Solid carbide construction for rigidity and wear resistance
• TiCN coating for improved hardness and thermal resistance
• 0.02-inch corner radius end geometry for edge durability and reduced chipping
• 40-degree helix angle promotes efficient chip evacuation
• 4-flute design balances material removal rate with finish quality
• Single-end, right-hand cut and flute direction for standard machining setups

Compatibility

Designed as a direct-fit replacement for 1/2-inch shank end mill holders and collet chucks on vertical machining centers, horizontal mills, and knee mills accepting Series 120 solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and power is locked out before changing tooling. Seat the shank to the minimum recommended engagement depth in the collet or end mill holder and torque the retention hardware to the holder manufacturer's specification. Inspect the cutting edges and coating condition before each use.
