Accupro 12182468 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 12182468 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 1/4 inch mill diameter, a 3/4 inch length of cut, and a 0.01 inch corner radius that reduces stress concentrations at the base of milled features. The AlTiN coating provides thermal resistance and extends tool life in high-temperature cutting applications. With 4 spiral flutes, right-hand cutting direction, and a 40-degree helix angle, this end mill delivers efficient chip evacuation and smooth surface finishes. It is manufactured from micrograin solid carbide for dimensional stability and wear resistance.

This end mill is suited for milling ferrous metals, hardened steels, stainless alloys, and similar materials in CNC machining centers and manual mills. The centercutting design allows for plunge entry in addition to standard peripheral and slot milling. The single-end configuration with a 1/4 inch shank diameter fits standard toolholders commonly used in job shops, tool rooms, and production machining environments. It is well-suited for finish milling applications where a controlled corner radius is required to meet part print tolerances.

Key Features

• 0.01 inch corner radius reduces corner chipping and stress concentration in milled parts
• AlTiN coating provides high heat resistance for dry or high-speed cutting in ferrous materials
• 4 spiral flutes with right-hand cut and 40-degree helix for efficient chip flow
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Micrograin solid carbide construction for tight tolerances and extended tool life
• 2-1/2 inch overall length with 1/4 inch shank fits standard collet and toolholder systems

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual mills accepting a 1/4 inch shank end mill.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholder torque and runout procedures per the machine manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank engagement depth meets toolholder minimum requirements before tightening. Confirm corner radius tolerance and diameter tolerance requirements against part print before beginning a production run.
