Harvey Tool 985050 Corner Rounding End Mill 1/4 in 3 Flute

Product Description

The HARVEY TOOL 985050 is a corner rounding end mill designed to machine radius profiles on workpiece edges in milling applications. With a 1/4-inch cutting diameter and 3-flute geometry, it produces smooth, consistent corner radii on ferrous and non-ferrous materials. The right-hand cutting direction and right-hand flute spiral are standard for conventional CNC milling setups. Machinists and tool-and-die professionals use this tool when part drawings call for edge-break radii in place of sharp chamfers or burrs. The 0.141-inch shank diameter fits into standard collet systems common to CNC machining centers and manual knee mills.

This end mill is suited for light-to-medium material removal on edges, slots, and profiles where a radiused corner is required by design. Typical applications include mold and die work, fixture fabrication, and precision component finishing in job shop and production environments. It is installed and operated by machinists working with CNC machining centers, manual mills, or die-grinding setups that accept this shank diameter.

Key Features

• 1/4-inch cutting diameter for small-radius corner profiling
• 3-flute design balances chip evacuation with surface finish quality
• Right-hand cut and right-hand flute helix for standard CNC milling spindles
• 0.141-inch shank diameter compatible with standard collet chucks
• Lightweight construction at 0.06 pounds for minimal tool-change impact

Compatibility

Designed as an OEM-style replacement or direct-application corner rounding end mill for use in CNC machining centers and manual milling machines that accept a 0.141-inch shank collet.

Installation Notes

Installation is performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet and torque the collet nut according to the collet manufacturer's specifications. Verify runout with a dial indicator before beginning the cut, as excessive runout will degrade edge quality and shorten tool life.
