Hertel 334-202080 Carbide Countersink 3/16 in 4 Flute

Product Description

The HERTEL 334-202080 is a solid carbide countersink designed for producing clean, accurate countersunk holes in metal and other hard materials. With a 3/16 inch head diameter, a 100-degree included angle, and 4 flutes, this tool delivers smooth cutting action and consistent seat geometry. The straight-cylindrical shank measures 3/16 inch in diameter, making it compatible with standard drill chucks and collet holders. It is suited for production and maintenance machining environments where hole preparation for flat-head fasteners demands repeatable results. Machinists, tool and die workers, and maintenance technicians are the primary users of this countersink.

This countersink is appropriate for use in general machining, metalworking, and fabrication applications where countersunk fastener seats are required. The 100-degree included angle accommodates a range of flat-head screw standards. The carbide construction supports use in harder workpiece materials where high-speed steel tooling may wear prematurely. It is sold individually and fits standard machine tool setups in both manual and CNC environments.

Key Features

• 3/16 inch head diameter for precise, small-diameter countersinking
• 100-degree included angle suits common flat-head fastener specifications
• 4 flutes provide smooth cutting and reduced chatter
• Solid carbide construction for extended tool life in hard materials
• Straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement or direct-use countersink for standard machine tool setups accepting a 3/16 inch straight-cylindrical shank.

Installation Notes

This countersink is installed by machinists or maintenance technicians using a drill press, milling machine, or CNC machining center. Secure the straight-cylindrical shank firmly in a compatible drill chuck or collet before use. Ensure the workpiece is properly clamped and the spindle speed is appropriate for the workpiece material and tool diameter. Inspect the cutting edges before each use and replace the tool if chipping or wear is observed.
