Accupro 314996 Corner Radius End Mill 3/4 in Zrn Carbide

Product Description

The ACCUPRO 314996 is a solid carbide corner radius end mill designed for precision milling operations in demanding shop environments. It measures 3/4 inch in diameter with a 1-5/8 inch length of cut and a 4-inch overall length. The tool features a ZrN (zirconium nitride) coating for improved wear resistance and heat reduction at the cutting edge. With a 0.060-inch corner radius and a 37-degree variable-helix-free spiral flute design, the 314996 delivers clean, accurate cuts on ferrous and non-ferrous materials. Machinists and CNC operators install this tool in standard 3/4-inch toolholders for finish and semi-finish milling passes.

This end mill suits CNC machining centers and manual mills used in production and job shop environments. The centercutting geometry allows plunge entry, making it effective for slot milling, pocket milling, and profiling operations. The right-hand cutting and right-hand flute direction are standard for conventional and climb milling setups. Micrograin solid carbide construction provides the rigidity needed for tight-tolerance work on hardened and abrasive materials. The single-end configuration is optimized for dedicated roughing or finishing passes where consistent edge geometry is critical.

Key Features

• ZrN coating reduces friction and extends tool life in high-wear applications
• 0.060-inch corner radius minimizes stress concentration and chipping at part corners
• 3-flute design balances chip evacuation and cutting stability
• Centercutting geometry enables direct plunge entry without a pilot hole
• Micrograin solid carbide substrate supports use in hard and abrasive workpiece materials
• Right-hand cut, right-hand spiral flute for standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or direct-use tool for standard 3/4-inch diameter end mill toolholders and collet chucks used in CNC machining centers and manual vertical mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before inserting or removing the tool from the toolholder. Ensure the shank is fully seated and the collet or set screw is torqued according to the toolholder manufacturer specifications. Verify runout with a dial indicator before initiating a cut to prevent premature edge failure.
