Accupro 39537 Square End Mill 5/32 in 2 Flute Tialn

Product Description

The ACCUPRO 39537 is a single-end square end mill designed for general-purpose milling operations in metalworking environments. Built from powdered metal and finished with a TiAlN coating, it delivers improved heat resistance and tool life compared to uncoated high-speed steel tooling. The 30-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. With a cutting diameter of 0.1563 inches and a 2-flute configuration, this end mill is suited for slotting, peripheral milling, and light profiling in ferrous and non-ferrous materials. It is installed by machinists and toolroom operators working in production and job-shop settings.

This end mill fits standard milling operations requiring a 3/8-inch shank and a compact cutting diameter. The 7/16-inch length of cut supports shallow-to-moderate depth passes, and the 2-5/16-inch overall length allows fitment in most vertical and horizontal milling machine spindles as well as CNC machining centers. The centercutting capability enables plunge entry directly into the workpiece without a pre-drilled start hole, expanding its range of application in die work, moldmaking, and general machining.

Key Features

• TiAlN finish for elevated heat resistance and extended tool life in ferrous materials
• Centercutting design allows direct plunge entry into the workpiece
• 30-degree helix spiral flute promotes efficient chip evacuation
• Right-hand cut and right-hand flute configuration for standard milling spindle rotation
• Powdered metal construction provides consistent grain structure and wear resistance
• 2-flute geometry supports slotting and profiling in tighter spaces

Compatibility

Designed as an OEM-style replacement or standard tooling selection for milling machines and CNC machining centers accepting a 3/8-inch straight shank end mill.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder rated for 3/8-inch shank tooling. Confirm runout within acceptable limits before beginning a cut. Always power down and lock out the spindle before changing tooling. Follow the machine manufacturer guidelines for feed rate, spindle speed, and depth of cut appropriate to the workpiece material and setup rigidity.
