Accupro 314854 Corner Radius End Mill 1/2 in Zrn Carbide

Product Description

The ACCUPRO 314854 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 0.5 inch mill diameter, a 1.25 inch length of cut, and a 3 inch overall length. The cutting end carries a 0.060 inch corner radius that reduces stress concentrations at the base of a cut and extends tool life in high-demand applications. A ZrN (zirconium nitride) coating improves hardness and wear resistance, making this end mill well suited for abrasive materials. This tool is installed and operated by machinists and CNC operators in production and job shop settings.

This end mill fits standard milling machines and CNC machining centers equipped with a 1/2 inch tool holder or collet. The corner radius geometry makes it appropriate for finishing and semi-finishing passes where a sharp inside corner would risk tool chipping or workpiece cracking. It is commonly used on ferrous and non-ferrous metals, hardened steels, and similar materials where a ZrN coating provides a performance advantage. Single-end configuration means the tool is used from one end only.

Key Features

• 0.060 inch corner radius reduces edge chipping and stress risers at cut transitions
• ZrN coating increases surface hardness and wear resistance for extended tool life
• Solid micrograin carbide construction provides rigidity and thermal stability
• 3-flute design balances chip evacuation and cutting edge strength
• Right-hand cut and right-hand spiral flute direction for standard CNC and manual mill setups
• Centercutting capability allows plunge entry directly into the workpiece

Compatibility

Designed for use in any milling machine or CNC machining center that accepts a 1/2 inch shank end mill. Shank diameter tolerance is +0.0001 to -0.0004 inches; verify collet or holder specs before installation.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or tool holder to the recommended gauge line depth and torque the retention mechanism per the machine tool manufacturer specifications. Inspect the cutting edges and corner radius for chips or wear before each use.
