Accupro 314167 Corner Radius End Mill 1 in Zrn Carbide

Product Description

The ACCUPRO 314167 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. It features a 1 inch diameter, a 1.25 inch length of cut, and a 6 inch overall length, making it well suited for extended-reach applications where standard-length tools cannot access the workpiece. The 0.090 inch corner radius reduces stress concentrations at the cutting edge and produces a consistent radius on workpiece corners. A ZrN (zirconium nitride) coating provides heat resistance and surface hardness to extend tool life in abrasive and hard materials. This end mill is centercutting, allowing plunge entry into the workpiece.

This tool is intended for use in CNC machining centers and manual milling machines where extended reach into pockets, cavities, or deep-wall features is required. The 3.375 inch reach length and 0.950 inch neck diameter support deep-pocket milling with reduced deflection. The 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces on the workpiece. Typical applications include mold and die work, aerospace component machining, and general-purpose metalworking where corner radii and extended reach are both specified.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• ZrN coating improves surface hardness and thermal resistance during high-speed cutting
• 0.090 inch corner radius reduces edge chipping and produces consistent corner geometry
• Extended reach design with 3.375 inch reach length for deep-pocket and cavity work
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility

Compatibility

Designed as a single-end corner radius end mill with a 1 inch shank diameter, compatible with standard ER, Weldon, and hydraulic toolholders sized for 1 inch shank tooling on CNC milling machines and machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before mounting or removing the end mill. Verify toolholder runout and clamping torque per the toolholder manufacturer specifications before cutting. Extended-reach end mills are more susceptible to deflection at aggressive feed rates, so confirm cut parameters against the material and depth of cut before production use.
