Harvey Tool 67839 Corner Rounding End Mill 1/8 in 2 Flute

Product Description

The HARVEY TOOL 67839 is a double-end corner rounding end mill designed to produce precise radius profiles on workpiece edges. Built from solid carbide, this tool delivers the rigidity and wear resistance required for consistent edge-breaking and radius milling in production environments. The 1.00 mm (0.0390 inch) radius and 0.1250 inch mill diameter make it well suited for small-feature work where dimensional accuracy is critical. The bright, uncoated finish keeps the cutting geometry clean and allows for direct inspection of the edge condition. With two flutes and a double-end configuration, this tool offers flexibility and extended service life on the bench.

The 67839 is used in precision machining applications where controlled corner radii are required on metal or composite workpieces. It fits standard 1/8 inch collets and tool holders, making it compatible with CNC machining centers, manual mills, and high-speed spindles. The flared series geometry is appropriate for edge profiling passes on tight-tolerance parts. Machinists working on aerospace, medical, mold, and general precision components will find this end mill suitable for finishing passes where a clean, uniform radius is the objective.

Key Features

• 1.00 mm (0.0390 inch) corner radius for small-feature edge profiling
• Solid carbide construction for rigidity and extended tool life
• Double-end design provides two usable cutting ends per tool
• 2-flute configuration supports chip evacuation in finishing passes
• Bright, uncoated finish allows visual edge inspection between uses
• 0.5000 inch tip diameter suits narrow profiling and edge work

Compatibility

Designed as an OEM-style replacement or direct-use tool for applications requiring a 1/8 inch shank corner rounding end mill in the Corner Rounding End Mills 2 and 4 Flute Flared series.

Installation Notes

Installation is performed by a qualified machinist using a properly sized 1/8 inch collet or end mill holder. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Confirm runout with a dial indicator after seating the tool to avoid radius inconsistency on the finished part. Follow the machine manufacturer and tooling manufacturer feeds and speeds guidelines for solid carbide end mills at the applicable diameter.
