Harvey Tool 46093-C3 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The HARVEY TOOL 46093-C3 is a double-end corner rounding end mill designed to produce precise radiused edges on workpiece corners in milling operations. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers strong wear resistance and heat tolerance in ferrous and hardened materials. The cutter produces a 3/32 inch radius profile on a 1/4 inch diameter body with a tip diameter of approximately 0.047 inches. With a 2-flute geometry and 2.0 inch overall length, it is suited for finishing passes and edge-break work on precision components. Machinists and CNC operators in tool-and-die, aerospace, and general metalworking shops are the primary users of this tool.

This end mill is applied in CNC milling centers and manual knee mills where consistent corner radii are required on metal parts. The double-end configuration extends usable tool life by providing two cutting ends on a single shank. Common applications include edge finishing on steel, stainless steel, titanium, and other hard alloys where the AlTiN coating reduces galling and extends tool life at elevated cutting temperatures. The 1/4 inch shank diameter fits standard collets and toolholders commonly found in small-to-medium machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves heat resistance and extends tool life in ferrous alloys
• Double-end design provides two usable cutting ends per tool
• 3/32 inch corner radius for consistent, repeatable edge profiling
• 2-flute geometry suited for finishing passes and edge-break operations
• 1/4 inch shank diameter compatible with standard collet systems

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with standard 1/4 inch collets or 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 or CNC operator with the machine fully powered down and the spindle locked before tool changes. Ensure the shank is fully seated and properly torqued in the collet or toolholder per the machine manufacturer's specifications. Inspect the cutting edges and coating for chips or wear before each use. Do not use this tool for plunge cutting unless the specific operation has been validated for this geometry.
