Harvey Tool 68187 Corner Rounding End Mill 3/16 in 4 Flute

Product Description

The HARVEY TOOL 68187 is a double-end, solid carbide corner rounding end mill designed to produce consistent radius profiles on workpiece edges in precision machining applications. With a 3/16 inch radius, 1/2 inch mill diameter, and four flutes, this tool delivers smooth, repeatable corner forms on ferrous and non-ferrous materials. The bright/uncoated finish makes it well-suited for use in aluminum and other non-ferrous alloys where coating adhesion is not required. The double-end configuration extends tool life by providing two usable cutting ends. At 3 inches overall length with a 1/2 inch shank diameter, it fits standard toolholders and milling machine spindles used in job shop and production environments.

This end mill is used in CNC machining centers and manual milling setups where edge rounding, radius blending, or profile work is required. The flared corner rounding geometry is suited for finishing passes on part edges to eliminate sharp corners, reduce stress concentrations, or meet drawing callouts for specific radii. Machinists, tool and die makers, and CNC operators working in job shops, aerospace component work, and general precision machining will find this tool appropriate for edge preparation on a wide range of materials.

Key Features

• 3/16 inch radius geometry for accurate, consistent edge rounding
• Four-flute design improves surface finish and chip evacuation
• Double-end construction provides two cutting ends for extended tool use
• Solid carbide construction offers rigidity and wear resistance
• Bright/uncoated finish suited for non-ferrous and general-purpose machining
• 1/2 inch shank diameter fits standard collets and end mill holders

Compatibility

Designed as an OEM-style corner rounding end mill compatible with standard 1/2 inch collets, shrink-fit holders, and end mill holders used on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into the toolholder to the recommended engagement depth before tightening. Verify runout with a dial indicator before cutting. Do not exceed the tool manufacturer's recommended feeds and speeds for the workpiece material, and never use a damaged or chipped cutting edge.
