Harvey Tool 21100 Corner Rounding End Mill 1/2 Inch 4 Flute

Product Description

The HARVEY TOOL 21100 is a solid carbide corner rounding end mill designed to produce precise radius profiles on workpiece edges. With a 0.10 mm corner radius and a 0.500 inch mill diameter, this double-end tool delivers consistent, repeatable results in ferrous and non-ferrous materials. The 4-flute geometry supports efficient chip evacuation and surface finish quality. The bright, uncoated finish makes it suitable for a wide range of general machining applications. Machinists and CNC operators working in precision job shops, aerospace, and medical manufacturing rely on tools of this type for clean edge-breaking and decorative or functional radius work.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills capable of holding a 1/2 inch shank. The double-end configuration provides two usable cutting ends, extending tool life and value per unit. At 3 inches overall length with a 0.248 inch tip diameter, it fits standard 1/2 inch collet and end mill holders commonly found in production and prototype environments. It belongs to the Corner Rounding End Mills - 2 and 4 Flute - Flared series from HARVEY TOOL, intended for applications requiring a controlled, precise radius on part edges and corners.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked, de-energized state. Secure the shank in a properly sized, clean 1/2 inch collet or end mill holder to the holder manufacturer's specified pull-out force guidelines. Inspect the cutting edges for chips or damage before use. Follow your machine tool builder's guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material and setup rigidity.
