Value Collection KP84204 Countersink 82 Deg 7/16 in Hss

Product Description

The VALUE COLLECTION KP84204 is a high-speed steel countersink designed to create clean, chamfered seat angles in metal and other materials. Built with an 82-degree included angle, it produces the standard countersink profile required for flat-head fasteners. The 1/4-inch shank diameter fits standard drill chucks and quick-change holders common in machine shop and fabrication environments. With a 7/16-inch head diameter and a maximum cutting diameter of 0.4000 inches, this tool handles light countersinking tasks on the drill press or hand drill. Machinists, fabricators, and maintenance technicians are the primary users of this style of countersink.

This countersink is suited for use in general metalworking, light fabrication, and maintenance applications where a consistent 82-degree chamfer is required for flat-head screws and machine screws. The single-piece high-speed steel construction handles standard ferrous and non-ferrous materials. It is a compact, single-unit tool appropriate for bench work, drill press setups, and portable drill applications in shop or field environments.

Installation Notes

Machinists and fabricators install this countersink by securing the 1/4-inch shank in a drill chuck or quick-change holder on a drill press or handheld drill. Ensure the workpiece is clamped securely before operation to prevent movement during cutting. Use appropriate cutting fluid when countersinking harder metals to extend tool life. Always power down and de-energize the machine before changing or adjusting tooling.
