Harvey Tool 44187-C3 Corner Rounding End Mill 4 Flute Altin

Product Description

The HARVEY TOOL 44187-C3 is a double-end, solid carbide corner rounding end mill designed for precision edge profiling on metal workpieces. It features a 3/16 inch radius and a 5/8 inch mill diameter, with a matching 5/8 inch shank diameter for secure tool holder engagement. The AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in demanding cutting applications. With 4 flutes and a 1/4 inch tip diameter, this end mill is well suited to high-speed finishing passes where consistent, clean corner geometry is required. Machinists and CNC tool-and-die professionals are the primary users of this tool.

This corner rounding end mill is used in CNC machining centers and manual milling operations where broken or radiused edges are specified on machined components. It is appropriate for use on ferrous metals, stainless steels, and hardened alloys where an AlTiN coating provides thermal and wear advantages. The double-end configuration allows the tool to be reversed when one end shows wear, extending usable service life. Typical applications include aerospace components, mold and die work, and precision production machining where edge consistency is critical.

Key Features

• 3/16 inch corner radius delivers consistent, repeatable edge profiles
• AlTiN coating provides elevated heat resistance for hard-material and high-speed cutting
• 4-flute geometry supports efficient chip evacuation and improved surface finish
• Double-end design extends tool service life by offering two usable cutting ends
• Solid carbide construction provides rigidity and dimensional stability under cutting loads
• 5/8 inch shank diameter compatible with standard ER and hydraulic tool holders

Compatibility

Designed as an OEM-specification solid carbide corner rounding end mill in the HARVEY TOOL Corner Rounding End Mills 2 and 4 Flute Unflared series, compatible with standard 5/8 inch tool holders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the tool holder depressurized or released before changing tooling. Ensure the shank is clean and fully seated in the holder to the recommended gauge line depth before tightening. Follow the machine tool manufacturer torque specifications for the specific holder style in use.
