Value Collection 28625 Countersink 1/4 in 82 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION 28625 is a single-end countersink designed for deburring holes and chamfering fastener seats in metal, wood, and composite materials. Machined from high speed steel, it delivers consistent cutting performance across production and maintenance applications. The 82-degree included angle matches the standard angle for flat-head machine screws and bolts used throughout industrial and mechanical assembly. With six flutes, the tool produces a smooth, chatter-free finish at moderate spindle speeds. The 1/4-inch shank fits standard drill chucks and quick-change holders common on drill presses, CNC mills, and hand drills. Machinists, millwrights, fabricators, and general maintenance technicians keep this tool on hand for everyday countersinking tasks.

This countersink is suited for light to medium-duty countersinking in ferrous and non-ferrous metals, plastics, and wood. The 82-degree angle is the correct geometry for flush-seating standard flat-head fasteners per ANSI specifications. It performs well in bench drill press work, manual milling operations, and portable drill applications where a controlled, finished chamfer is required before fastener installation. The 1/4-inch shank diameter keeps the tool compatible with the widest range of available toolholding systems in a typical shop environment.

Compatibility

Designed as a standard single-end countersink for use with drill presses, milling machines, and hand drills equipped with a 1/4-inch or larger chuck capacity.

Installation Notes

This tool is installed and operated by machinists, fabricators, and maintenance technicians. Secure the shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Run the tool at moderate spindle speeds with light feed pressure to avoid chatter and overheating, especially in harder metals. Inspect the cutting edges before use and replace the tool if flutes show signs of wear or chipping.
