Harvey Tool 986020 Dovetail Cutter 5/16 in Solid Carbide

Product Description

The HARVEY TOOL 986020 is a solid carbide dovetail cutter designed for machining dovetail slots and undercut profiles in a wide range of workpiece materials. Built with a 20-degree included angle and a 5/16-inch cut diameter, this cutter produces clean, accurate dovetail geometry in a single pass. The 3-flute design balances chip evacuation with edge strength, making it well-suited for both slotting and profile work in ferrous and non-ferrous metals, plastics, and composites. The bright uncoated finish is appropriate for applications where coating interaction with the workpiece material is a concern. At 0.1 pounds, it is a compact tooling solution for small-feature dovetail work.

This cutter is used in CNC machining centers and manual milling operations where dovetail features are required for slide ways, T-slots, interlocking joints, and fixture components. The 5/16-inch shank diameter fits standard ER collet chucks and end mill holders found in typical shop tooling setups. It is appropriate for light-to-medium cutting depths in precision machining environments and is commonly selected for prototype work, short-run production, and fixture fabrication where small-diameter dovetail geometry is specified.

Key Features

• 20-degree included angle for standard dovetail slot geometry
• 5/16-inch cut diameter with 0.3120-inch cutting width for precise undercut profiling
• Solid carbide construction for rigidity and wear resistance
• 3-flute configuration balances chip clearance and cutting edge stability
• Bright uncoated finish suitable for non-ferrous metals, plastics, and composites
• 5/16-inch shank diameter compatible with standard collet and end mill holder tooling

Compatibility

Designed as an OEM-style solid carbide dovetail cutter for use in CNC and manual milling machines accepting a 5/16-inch shank diameter toolholder.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with rotating cutting tool safety. Secure the shank fully in a properly sized collet or end mill holder and confirm runout before cutting. Always power down the spindle and confirm the tool is stationary before making any toolholder adjustments. Follow the machine tool manufacturer and tooling manufacturer guidelines for speeds and feeds when selecting operating parameters for this cutter.
