Accupro 95168522 Corner Radius End Mill 3/8 in 5 Flute

Product Description

The ACCUPRO 95168522 is a solid carbide corner radius end mill designed for precision milling in ferrous and hardened materials. With a 3/8 inch diameter, 0.0300 inch corner radius, and five flutes, it delivers smooth cutting action and longer tool life in demanding applications. The AlTiN coating provides high heat resistance and hardness, making this end mill well suited for high-speed dry machining and difficult-to-cut alloys. A 45-degree helix angle promotes chip evacuation and reduces cutting forces. This tool is intended for use by machinists and tool-and-die professionals working on CNC mills and machining centers.

This end mill is used in general metalworking, mold and die work, and precision component machining where a controlled corner radius is required to reduce stress concentrations. With a 1 inch length of cut and 2.5 inch overall length, it fits standard toolholding on vertical and horizontal machining centers. The single-end, centercutting design allows both peripheral and plunge milling operations. It is appropriate for production and job-shop environments handling steel, stainless, and hardened workpieces.

Key Features

• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• Five-flute geometry increases feed rates and surface finish quality compared to four-flute designs
• 0.0300 inch corner radius reduces chipping on part edges and extends cutter life
• 45-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Micrograin solid carbide substrate provides rigidity and wear resistance
• Centercutting design supports both ramp and plunge entry cuts

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual mills accepting a 3/8 inch straight shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before loading or changing tooling. Use a properly sized collet or end mill holder torqued according to the toolholder manufacturer specifications. Verify runout after installation before beginning cuts to protect both the workpiece and the cutter.
