Accupro 95169993 Corner Radius End Mill 3/8 in 5 Flute

Product Description

The ACCUPRO 95169993 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. It features a 3/8-inch diameter, a 1-inch length of cut, and a 2.5-inch overall length. The tool carries an AlCrTiN coating for extended tool life under high-heat cutting conditions. With a 5-flute, right-hand spiral geometry, a 38-degree helix angle, and a variable index design, the 95169993 delivers smooth chip evacuation and reduced chatter. It is centercutting and built from micrograin solid carbide for rigidity and edge retention. Licensed machinists and CNC operators install this tool in production and job-shop environments.

This end mill is suited for ferrous and hardened material milling operations where corner integrity and surface finish are critical. The 0.030-inch corner radius protects the cutting edge during radial and axial passes, making it a practical choice for profiling, slotting, and finishing operations on steel, stainless, and similar alloys. The straight-cylindrical shank seats directly in standard collet chucks and end mill holders with a 3/8-inch bore.

Key Features

• AlCrTiN coating provides high heat resistance and extended wear life in ferrous cutting
• 5-flute geometry increases feed rates and improves surface finish compared to 4-flute designs
• 0.030-inch corner radius reduces edge chipping and extends tool life at corner transitions
• Variable index flute spacing reduces harmonic chatter during aggressive cuts
• Centercutting design allows plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate maintains edge sharpness under high cutting loads

Compatibility

Designed as an OEM-style replacement end mill for use in standard 3/8-inch collet chucks, shrink-fit holders, and end mill holders across CNC machining centers and manual mills accepting straight-cylindrical shank tooling.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine in a locked-out state per applicable shop safety procedures. Seat the shank fully into the holder to the minimum engagement depth recommended by the holder manufacturer before torquing the collet nut or set screw. Inspect the corner radius and cutting edges for chips or wear before each use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
