Harvey Tool 45305-C3 Corner Rounding End Mill 1/8 in 2 Flute

Product Description

The HARVEY TOOL 45305-C3 is a double-end corner rounding end mill designed for precise edge-breaking and radius profiling on machined parts. Built from solid carbide with an AlTiN coating, it produces a 0.005-inch corner radius on workpieces where tight tolerances and surface finish matter. The 1/8-inch diameter and 2-flute geometry make it suited for small-feature work in harder materials where heat resistance and tool rigidity are critical. Machinists and toolroom operators install this end mill in CNC machining centers and manual mills requiring accurate, repeatable edge geometry.

This end mill is intended for applications where a controlled, small-radius corner break is required on ferrous and non-ferrous materials. The AlTiN coating improves heat resistance and extends tool life in dry or minimal-lubrication cutting conditions. The double-end configuration provides two usable cutting ends, making it a practical choice for production environments focused on tooling cost control. It fits standard 1/8-inch collets and tool holders used across vertical and horizontal machining centers.

Key Features

• 0.005-inch corner radius for precise, repeatable edge profiling
• Solid carbide construction provides rigidity and wear resistance in hard materials
• AlTiN coating improves thermal resistance for dry and near-dry cutting conditions
• Double-end design delivers two usable cutting ends per tool
• 2-flute geometry suits small-diameter finish passes and tight-feature work
• 1/8-inch shank diameter fits standard collets and shrink-fit holders

Compatibility

Designed for use in CNC machining centers and manual mills equipped with standard 1/8-inch collets or tool holders. Part of the Harvey Tool Corner Rounding End Mills - 2 and 4 Flute - Flared series.

Installation Notes

Installation should be performed by a qualified machinist familiar with small-diameter carbide tooling. Ensure the spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Solid carbide tooling is brittle and should not be used in holders with excessive runout, as lateral shock can cause chipping or fracture. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the workpiece material and coating type.
