Accupro 314602 Square End Mill 1/4 in 3 Flute Carbide Zrn

Product Description

The ACCUPRO 314602 is a single-end square end mill designed for precision milling operations in metal, composites, and similar materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cutting applications. The tool features a 1/4 inch cutting diameter, a 1 inch length of cut, and a 37-degree helix angle that promotes efficient chip evacuation and smooth cutting action. A zirconium nitride (ZrN) coating reduces friction and extends tool life in abrasive materials. This end mill is installed and used by machinists and tool-and-die professionals working with CNC machining centers and manual milling machines.

This end mill is suited for general-purpose milling, profiling, slotting, and side milling in shop and production environments. The 1/4 inch shank diameter fits standard collets and end mill holders commonly found on vertical milling machines and machining centers. With a 2.5 inch overall length and no extended reach, it provides a stable, low-deflection setup for typical depth-of-cut requirements in ferrous and non-ferrous workpieces.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• ZrN coating reduces friction and increases wear resistance in abrasive materials
• 37-degree right-hand spiral helix angle promotes efficient chip evacuation
• 3-flute geometry balances chip clearance and cutting surface contact
• Center-cutting design allows plunge entry into workpieces
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any milling setup accepting a 1/4 inch shank end mill with a standard ER or end mill collet holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended insertion depth and torque the retention nut per the holder manufacturer specification. Verify runout with a dial indicator before initiating a cut.
