Harvey Tool 68007-C3 Corner Rounding End Mill 1/8 in 4 Flute

Product Description

The HARVEY TOOL 68007-C3 is a double-end, 4-flute corner rounding end mill designed for precision edge-breaking and radius profiling in metal and hard material applications. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), this tool handles high-temperature cutting environments typical of ferrous metals and hardened steels. The 0.0070-inch corner radius produces clean, consistent edge profiles without secondary deburring operations. At 0.1250 inches in diameter with a matching 0.1250-inch shank, this is a small-diameter tool intended for tight geometries and fine detail work in machined components.

This end mill is suited for CNC milling operations in job shops, tool rooms, and production environments where precise corner radii are required on ferrous and non-ferrous workpieces. The double-end configuration delivers two usable cutting ends per tool, extending service life before replacement. The flared series geometry supports smooth radial engagement, making it a practical choice for finishing passes on mold components, fixtures, and tight-tolerance machined parts where edge condition matters.

Key Features

• 0.0070-inch corner radius for fine, precise edge rounding on machined parts
• AlTiN coating provides high heat resistance and extended tool life in ferrous cutting applications
• Double-end design yields two cutting ends per tool for improved value per tool change
• 4-flute configuration supports efficient chip evacuation and smooth surface finish
• Solid carbide construction delivers rigidity and dimensional stability at small diameters
• Tip diameter of 0.1070 inches enables access to tight geometries and close-clearance features

Compatibility

Designed for use in standard CNC milling machine collet chucks or tool holders accepting a 1/8-inch shank diameter, as part of the Corner Rounding End Mills 2 and 4 Flute Flared series by HARVEY TOOL.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC setup technician. Before tool installation, ensure the spindle is fully powered down and locked out per shop lockout/tagout procedures. Seat the shank fully and evenly in the collet or tool holder and verify runout before engaging the cut. At this diameter, avoid side-loading or interrupted cuts that can cause tool deflection or breakage.
