Accupro 314775 Square End Mill 13/32 in 3 Flute Carbide Zrn

Product Description

The ACCUPRO 314775 is a solid carbide square end mill designed for precision milling in metal-cutting applications. It features a 13/32 inch (0.4063 inch) cutting diameter and a 9/16 inch length of cut, with a 7/16 inch shank diameter and a 2-3/4 inch overall length. The three-flute geometry paired with a 37-degree right-hand helix angle promotes efficient chip evacuation and reduces heat buildup during cutting. A ZrN (zirconium nitride) coating adds surface hardness and lubricity, extending tool life on ferrous and non-ferrous workpiece materials. The micrograin carbide substrate provides rigidity and edge retention in demanding cut conditions.

This end mill suits general-purpose profiling, slotting, and peripheral milling operations on machining centers and CNC mills. It is centercutting, which allows plunge entry into the workpiece. The single-end, right-hand cutting direction configuration is standard for most vertical and horizontal milling setups. Typical users include machinists and tool-and-die professionals working with steel, stainless steel, cast iron, and similar materials in job shop or production environments.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• ZrN coating increases surface hardness and reduces friction at the cutting edge
• 37-degree right-hand helix angle supports chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry without a pre-drilled hole
• 3-flute configuration balances chip clearance and cutting stability
• Spiral flute type for continuous, consistent engagement along the length of cut

Compatibility

Designed as a standard shank solid carbide square end mill for use in CNC machining centers and manual mills accepting a 7/16 inch shank diameter in a collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before mounting. Secure the shank fully within the collet or holder to the minimum insertion depth recommended by the holder manufacturer. Verify runout with a dial indicator before beginning a cut to avoid premature tool wear or breakage.
