Harvey Tool 44093-C3 Corner Rounding End Mill 1/2 in 4 Flute

Product Description

The HARVEY TOOL 44093-C3 is a double-end corner rounding end mill designed for producing consistent radius edges on ferrous and non-ferrous workpieces. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers high heat resistance and extended tool life in demanding cutting environments. The 4-flute configuration provides a good balance of chip evacuation and finish quality. At 0.5 inches in diameter with a 3/32-inch corner radius and a 0.25-inch tip diameter, this tool is suited for precision edge-breaking and profile work in CNC machining operations. Qualified machinists and tool-and-die technicians are the primary users.

This end mill is appropriate for milling operations requiring controlled radius profiles on part edges, pockets, and contours. The double-end design extends usable tool life before replacement is needed. With a 1/2-inch shank diameter, it mounts directly in standard ER collet chucks, hydraulic holders, or shrink-fit tooling commonly used on vertical and horizontal machining centers. Typical applications include finishing passes on hardened steel, stainless, and high-temperature alloys where AlTiN coating performance is advantageous.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and longer tool life at high cutting speeds
• Double-end design doubles usable cutting ends per tool
• 4-flute geometry balances chip clearance with surface finish quality
• 3/32-inch corner radius for consistent, repeatable edge profiling
• 1/4-inch tip diameter allows access to tighter inside corner geometry

Compatibility

Designed as an OEM-style corner rounding end mill for use in standard 1/2-inch diameter CNC toolholders; 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 shop safety protocols. Power down and lock out the spindle before seating or removing the tool from the holder. Ensure the shank is fully seated and the collet or chuck is torqued to the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use, as solid carbide tools can fracture if run with pre-existing edge damage.
