Accupro 314711 Corner Radius End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 314711 is a single-end, corner radius end mill designed for precision milling in ferrous and non-ferrous metal applications. Built from micrograin solid carbide and coated with zirconium nitride (ZrN), it delivers hardness and wear resistance suited to demanding cutting conditions. The 3/8-inch diameter tool carries a 0.0200-inch corner radius that reduces chipping at part edges and extends tool life in interrupted cuts. With three right-hand spiral flutes and a 37-degree helix angle, it promotes efficient chip evacuation and smooth surface finishes. Licensed machinists and CNC operators handling precision component work will find this tool sized for detailed contouring and profiling passes.

This end mill fits standard 3/8-inch collet or end mill holders and is suited to vertical machining centers and CNC mills running ferrous alloys, stainless steel, aluminum, and similar materials. Its regular-length geometry and 1/2-inch length of cut make it appropriate for shallow-to-moderate depth passes in component profiling, slotting, and contouring. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, expanding its use in die and mold work as well as general precision machining environments.

Key Features

• Micrograin solid carbide construction for high hardness and edge retention
• ZrN coating increases surface hardness and reduces friction during cutting
• 0.0200-inch corner radius reduces edge chipping and extends tool life
• 37-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting design permits direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed for use in standard 3/8-inch collet chucks and end mill holders on CNC vertical machining centers and manual knee mills configured for right-hand rotation tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle drive before inserting or removing the tool from the holder. Seat the shank fully within the collet or holder to the recommended engagement depth before tightening. Inspect the cutting edges and corner radius for chips or wear before each use, and do not exceed the manufacturer-recommended depth of cut for the workpiece material.
