Accupro 95168544 Corner Radius End Mill 7/16 in 4 Flute

Product Description

The ACCUPRO 95168544 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hardened materials. With a 7/16 inch (0.4375 inch) mill diameter, a 0.0200 inch corner radius, and 4 right-hand spiral flutes, this tool delivers smooth corner geometry and extended tool life in demanding cutting environments. The AlTiN coating provides high heat resistance and hardness, making it well-suited for dry or high-speed machining. It is a single-end, centercutting design with a variable helix for reduced chatter. Machinists and CNC operators in production shops, tool rooms, and job shops install and run this tool.

This end mill is used in milling applications where a controlled corner radius is required on part features such as pockets, slots, and profiled edges. The stub length-of-cut configuration at 9/16 inch keeps deflection low and rigidity high, making it a strong choice for high-feed side milling and finish passes. The 7/16 inch shank diameter matches the mill diameter for direct collet or end mill holder mounting. Micrograin carbide construction supports tight tolerances on hardened steels, stainless, and similar materials.

Key Features

• 0.0200 inch corner radius for controlled edge blending on milled features
• AlTiN coating for elevated heat resistance during high-speed or dry machining
• Variable helix flute design reduces vibration and chatter during cutting
• Centercutting geometry allows plunge entry into workpiece
• Micrograin solid carbide substrate supports tight mill diameter tolerance of +0.000000/-0.002000 inches
• Right-hand cutting direction compatible with standard CNC spindle rotation

Compatibility

Designed as a direct-mount replacement or new-installation end mill for standard 7/16 inch collets, shrink-fit holders, or end mill holders used in CNC machining centers and manual mills.

Installation Notes

Installation is performed by machinists or CNC setup technicians. The machine spindle must be fully stopped and locked out before mounting or removing the tool from its holder. Verify holder bore and collet size match the 7/16 inch shank diameter and confirm runout with a dial indicator before cutting. Follow the tool manufacturer and machine builder recommendations for speed and feed parameters based on workpiece material.
