Harvey Tool 44125-C3 Corner Rounding End Mill 1/8 in Radius

Product Description

The HARVEY TOOL 44125-C3 is a double-end, four-flute corner rounding end mill designed for producing consistent radius profiles on machined workpieces. Manufactured from solid carbide and finished with an AlTiN (Aluminum Titanium Nitride) coating, this tool handles high-temperature cutting environments and abrasive materials without sacrificing edge life. The 1/8 inch radius profile, combined with a 5/8 inch mill diameter and 1/4 inch tip diameter, makes it well-suited for radiusing edges, blending transitions, and finishing contoured surfaces on precision components. It is installed and operated by machinists and CNC programmers working in job shop, aerospace, medical, and general metalworking environments.

This end mill fits applications requiring a controlled 1/8 inch corner radius on ferrous and non-ferrous metals, hardened steels, and high-temp alloys where an AlTiN coating provides thermal protection. The double-end configuration extends tool life by offering two usable cutting ends. It is commonly used in vertical and horizontal CNC machining centers for edge-breaking, radius milling, and profile finishing operations where surface finish and dimensional accuracy are critical. The 5/8 inch shank diameter is compatible with standard ER and end mill holders used in production machining setups.

Key Features

• 1/8 inch radius profile for consistent edge rounding and contour blending
• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating improves heat resistance and extends tool life in dry and high-speed machining
• Double-end design provides two cutting ends, increasing value per tool
• Four flutes deliver improved surface finish and efficient chip evacuation
• 5/8 inch shank diameter fits standard end mill and ER-style toolholders

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 5/8 inch shank diameter. Part of the HARVEY TOOL Corner Rounding End Mills 2 and 4 Flute Unflared series.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and the tool is secured with proper torque to the toolholder manufacturer specification before operation. Verify runout with a dial indicator after seating to confirm concentricity. Follow all applicable machine guarding and PPE requirements per shop safety standards.
