Harvey Tool 68015-C3 Corner Rounding End Mill 3/16 Inch

Product Description

The HARVEY TOOL 68015-C3 is a double-end corner rounding end mill designed for edge-profiling operations on ferrous and non-ferrous metals. Built from solid carbide, it carries a 1/64-inch radius and a 3/16-inch mill diameter across four flutes, delivering smooth, consistent radii on part edges in a single pass. The AlTiN coating adds thermal resistance and surface hardness, extending tool life in high-speed and dry-cutting applications. At 2 inches overall length with a matching 3/16-inch shank diameter, the geometry suits close-tolerance work in CNC machining centers where rigidity and runout control are priorities. The double-end configuration allows both ends to be used before replacement, reducing tooling cost per edge.

This end mill is suited for CNC milling operations requiring precise corner radii on workpieces machined in job shops, tool-and-die environments, and production machining cells. The AlTiN coating performs well in hardened steels, stainless steels, and cast iron, making it appropriate for both prototype work and production runs. Machinists and CNC operators install and operate this tool. The flared corner rounding profile matches Harvey Tool's 2-and-4-flute flared series for consistent edge-break and radius blending on part features.

Key Features

• Solid carbide construction provides stiffness and wear resistance in demanding cutting conditions
• AlTiN coating extends tool life in high-heat, dry, and hard-material cutting applications
• Double-end design yields two usable cutting ends per tool
• 4-flute geometry improves surface finish and chip evacuation compared to 2-flute alternatives
• 1/64-inch radius suited for fine edge-break and small-feature corner rounding
• 3/16-inch shank diameter fits standard ER collet chucks and end mill holders at that bore size

Compatibility

Part of the Harvey Tool Corner Rounding End Mills 2-and-4-Flute Flared series. Designed for use in CNC machining centers and milling machines equipped with a 3/16-inch collet or end mill holder. No specific machine model compatibility was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before loading or unloading the tool. Seat the shank fully and evenly in the collet or holder before torquing the nut to the tool-holder manufacturer's specification. Verify runout with a dial indicator after installation; excessive runout accelerates flute wear and degrades radius accuracy.
