Accupro 14796282 Corner Radius End Mill 1/4 in 3 Flute

Product Description

The ACCUPRO 14796282 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and excellent wear resistance. Built on a miniature series platform, this single-end, centercutting tool features a 1/4 inch mill diameter, a 0.03 inch corner radius, and 3 right-hand spiral flutes with a 30-degree helix angle. The bright/uncoated finish suits applications where coating buildup or heat transfer is a concern. At 4 inches overall length with an extended reach configuration, it handles deeper-access cuts while maintaining rigidity. Machinists and tool-and-die professionals working with CNC mills and manual knee mills will find this tool suited for finishing and semi-finishing passes in tight geometries.

This end mill is intended for use in small-part machining, mold and die work, and precision component manufacturing where a controlled corner radius is required to reduce stress concentrations and improve surface finish. The 3/8 inch length of cut and 1.25 inch reach length make it suitable for moderate-depth slot milling, profiling, and peripheral cutting in ferrous and non-ferrous materials. The micrograin carbide grade supports fine edge retention at higher surface speeds. This tool is appropriate for job shops, aerospace component shops, and medical device manufacturers working at close tolerances.

Key Features

• 0.03 inch corner radius reduces edge chipping and stress concentration at workpiece corners
• Solid micrograin carbide construction for extended edge life and dimensional stability
• 3 right-hand spiral flutes with 30-degree helix for efficient chip evacuation
• Centercutting geometry allows plunge entry into the workpiece
• Extended reach at 1.25 inches accommodates deeper-access milling operations
• Bright/uncoated finish compatible with a wide range of cutting fluids and materials

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 1/4 inch collets, ER collet chucks, and end mill holders on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist following safe tooling practices. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify shank runout with a dial indicator before production use. Follow the machine manufacturer and tooling manufacturer guidelines for clamping torque and stick-out length to avoid tool deflection or pullout during cutting.
