Accupro 14796224 Corner Radius End Mill 0.0312in 3 Flute

Product Description

The ACCUPRO 14796224 is a miniature corner radius end mill designed for precision milling operations requiring tight tolerances and a controlled edge radius. Built from micrograin solid carbide and coated with AlTiN, this tool handles hardened materials and high-temperature cutting environments. It features a 0.0312 inch mill diameter, a 0.005 inch corner radius, and a 0.046 inch length of cut. With 3 flutes and a 30-degree helix, it balances chip evacuation with surface finish quality. It is used by machinists and toolmakers working on CNC machining centers in die, mold, and precision component applications.

This end mill is suited for small-feature milling in ferrous and non-ferrous materials where a corner radius is needed to reduce stress concentration and improve tool life. The extended reach design, with a 0.156 inch reach length, allows access to recessed features and pockets. The 1/8 inch shank diameter makes it compatible with standard collet systems used in CNC vertical machining centers and high-speed spindle setups. It is a single-end, centercutting tool capable of plunge entry as well as peripheral and slot milling in miniature-scale work.

Key Features

• 0.005 inch corner radius reduces edge chipping and stress concentration at part corners
• AlTiN coating provides heat resistance and extends tool life in hardened and abrasive materials
• Micrograin solid carbide substrate supports tight tolerances: mill diameter tolerance +0.000 / -0.001 inch
• Extended reach with 0.156 inch reach length for access to recessed features
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand spiral flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct procurement option for miniature corner radius end mill applications in CNC machining centers using 1/8 inch collet or end mill holder systems.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the 1/8 inch shank in a properly sized collet or end mill holder and torque to the machine tool manufacturer's specification before use. Verify runout with a dial indicator before engaging the workpiece, as runout is especially critical at this diameter. Never exceed the tool manufacturer's recommended speed and feed parameters for the material being cut.
