Accupro 313000 Square End Mill 7/32 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313000 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide, it delivers hardness and edge retention well beyond standard high-speed steel tooling. The 7/32 inch (0.2188 inch) cutting diameter pairs with a 3/8 inch length of cut and a 45-degree helix angle for efficient chip evacuation and reduced cutting forces. A zirconium nitride (ZrN) coating adds surface hardness and lubricity, extending tool life in non-ferrous metals, aluminum alloys, and similar materials. This stub-length configuration provides added rigidity during aggressive cuts.

This end mill suits CNC machining centers, manual knee mills, and tool-and-die work where a small-diameter, short-flute tool is required. The 1/4 inch shank diameter fits standard collet chucks and end mill holders common in both production and job-shop environments. Its stub-length designation makes it appropriate for shallow pockets, slots, and profiling passes where tool deflection is a concern. Machinists and tooling specialists working with aluminum, brass, copper, and similar soft metals will find the ZrN coating particularly effective.

Key Features

• Micrograin solid carbide construction for high hardness and wear resistance
• ZrN coating improves surface lubricity and extends tool life in non-ferrous applications
• 45-degree helix angle promotes smooth chip flow and reduced cutting pressure
• Center-cutting capable, allowing plunge milling entries
• Right-hand cut and right-hand flute spiral for standard spindle rotation
• Stub-length design maximizes rigidity and minimizes deflection in short-reach applications

Compatibility

Designed as a standard 1/4 inch shank square end mill compatible with collet chucks, end mill holders, and milling arbors accepting 1/4 inch shank tooling on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and locked out before inserting or removing tooling from the collet or holder. Seat the shank to the recommended engagement depth specified by the collet or holder manufacturer. Verify runout with a dial indicator before beginning cuts, particularly when working to tight dimensional tolerances.
