Accupro 39536 Square End Mill 5/32 in 2 Flute Powdered Metal

Product Description

The ACCUPRO 39536 is a 2-flute square end mill designed for general-purpose milling in a wide range of metals and engineered plastics. Built from powdered metal, this single-end tool delivers consistent cutting performance in applications where high-speed steel is specified. The 5/32 inch cutting diameter pairs with a 30-degree helix angle and spiral flute geometry to promote chip evacuation and reduce cutting forces. The uncoated finish keeps the tool ready for use straight from the package. Centercutting capability allows plunge entry directly into the workpiece. This tool is installed by machinists and CNC programmers working in job shop, production, and maintenance machining environments.

This end mill is suited for peripheral milling, slotting, and light plunge operations on ferrous and non-ferrous materials. The 7/16 inch length of cut covers typical shallow-pocket and profile work. The 3/8 inch shank diameter fits standard ER collet chucks, end mill holders, and side-lock holders commonly found on vertical machining centers and manual knee mills. Right-hand cut and right-hand flute orientation follow the conventional spindle rotation standard for most milling machines.

Key Features

• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• 30-degree helix angle promotes smooth chip flow and reduces cutting pressure
• Powdered metal construction offers a cost-effective alternative to solid carbide in light-to-moderate applications
• Spiral flute design supports consistent chip evacuation during slotting and peripheral cuts
• Uncoated surface finish — no coating prep required before use
• Right-hand cut and right-hand flute for standard spindle direction compatibility

Compatibility

Designed as a direct-fit replacement for 3/8 inch shank end mill holders, ER collet chucks, and side-lock toolholders accepting a 3/8 inch shank. Compatible with vertical machining centers and manual milling machines running standard right-hand spindle rotation.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is locked out before changing tooling. Seat the shank fully into the holder to the minimum engagement depth recommended by the holder manufacturer before tightening. Verify runout with a dial indicator after installation; excessive runout shortens tool life and degrades surface finish.
