Harvey Tool 67650-C3 Corner Rounding End Mill 4 Flute Altin

Product Description

The HARVEY TOOL 67650-C3 is a double-end corner rounding end mill designed to produce precise convex radius profiles on workpiece edges. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), this tool handles demanding materials including hardened steels, stainless, and high-temp alloys. It runs a 0.05-inch radius on a 3/16-inch (0.1875-inch) mill diameter with a tip diameter of 0.058 inches. The 4-flute geometry improves surface finish and chip evacuation compared to 2-flute alternatives. Overall length is 2 inches with a 3/16-inch shank. Machinists and CNC operators use this tool in milling centers where edge-breaking and radius profiling are required to spec.

This end mill fits production and job-shop environments running vertical or horizontal machining centers. It is suited for edge radiusing on molds, dies, aerospace components, and precision mechanical parts where a consistent 0.05-inch corner radius must be held to tight tolerances. The double-end configuration provides two usable cutting ends, extending tool life before replacement is required. The flared series geometry is optimized for full-radius corner rounding passes rather than general-purpose side milling or slotting.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating improves heat resistance and extends tool life in dry or high-speed cutting conditions
• Double-end design provides two cutting ends per tool, reducing per-edge tooling cost
• 4-flute configuration delivers improved surface finish and balanced chip load
• 0.05-inch radius produces a consistent, repeatable convex edge profile
• Tip diameter of 0.058 inches supports access to tight-clearance workpiece geometry

Compatibility

Designed for use in CNC milling machines and machining centers accepting a 3/16-inch round shank. Part of the HARVEY TOOL Corner Rounding End Mills - 2 and 4 Flute - Flared series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a collet or end mill holder rated for the shank diameter before powering the spindle. Verify runout with a dial indicator after seating the tool. Follow machine manufacturer guidelines and applicable shop safety protocols when setting speeds and feeds for carbide tooling.
