Accupro 313453 Corner Radius End Mill 3/4 in 2 Flute Zrn

Product Description

The ACCUPRO 313453 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 0.75 inch mill diameter, a 1.625 inch length of cut, and a 4 inch overall length. The 0.1200 inch corner radius reduces stress concentrations at the cutting edge and extends tool life in contour and pocket milling. A ZrN (zirconium nitride) coating provides added hardness and lubricity, making this end mill well-suited for ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC tooling professionals on vertical and horizontal milling machines.

This end mill is used in both job shop and production machining environments where accurate corner radii and smooth floor finishes are required. The centercutting design allows plunge entry, making it practical for pocket and slot applications. The 45-degree helix angle and right-hand flute direction support efficient chip evacuation in a wide range of milling applications. The single-end, regular-length configuration is suited for standard reach setups on CNC machining centers and manual mills.

Key Features

• 0.1200 inch corner radius reduces edge chipping and improves surface finish at workpiece corners
• ZrN coating increases surface hardness and reduces built-up edge in ferrous and non-ferrous cutting
• Centercutting design enables plunge milling and slot entry without a pilot hole
• Solid micrograin carbide substrate provides rigidity and wear resistance
• Right-hand cut, right-hand spiral with 2 flutes for efficient chip evacuation
• Single-end configuration with 3/4 inch shank diameter for standard collet and end mill holder compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual vertical mills accepting a 3/4 inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout specifications. Power down and lock out the machine spindle before mounting or removing the tool. Seat the shank fully in the holder and verify runout with a dial indicator before engaging the workpiece. Follow applicable shop safety standards and machine tool codes when setting cutting parameters.
