Harvey Tool 977816-C3 Dovetail Cutter 40 Deg 1/4in Carbide Tialn

Product Description

The HARVEY TOOL 977816-C3 is a solid carbide dovetail cutter designed for machining dovetail slots, chamfers, and undercut features in a wide range of workpiece materials. The cutter features a 40-degree included angle, a 1/4-inch (0.2500-inch) cutting diameter, and a 5/32-inch (0.1560-inch) cutting width. A titanium aluminum nitride (TiAlN) coating provides thermal resistance and extended tool life in ferrous and non-ferrous applications. With 2 flutes and a 1/4-inch shank, this tool is sized for use in standard collet chucks and end mill holders on CNC machining centers and manual mills.

This dovetail cutter is suited for precision slot milling, fixture work, T-slot undercutting, and dovetail feature generation on machined components. Its compact 2-inch overall length and small-diameter geometry make it appropriate for tight-clearance operations and intricate part features. The TiAlN finish supports use in hardened steels, stainless steel, cast iron, and high-temperature alloys where heat buildup at the cutting edge is a concern. Machinists and CNC programmers in job shops, tool rooms, and production environments are the primary users of this cutter.

Key Features

• 40-degree included angle for standard dovetail slot geometry
• Solid carbide construction for rigidity and wear resistance
• TiAlN coating for thermal protection and extended tool life in ferrous materials
• 1/4-inch shank diameter compatible with standard collet and end mill holder systems
• 2-flute design for chip clearance in narrow cutting widths
• Compact 2-inch overall length for tight-clearance applications

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 1/4-inch collet chucks or end mill holders accepting a 1/4-inch shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Secure the 1/4-inch shank fully within the collet or holder to the recommended engagement depth to minimize runout. Verify cutting parameters — speed, feed, and depth of cut — against the tool manufacturer's published data for the specific workpiece material before initiating a cut.
