Value Collection SC40605S Countersink Set 5 Pc Hss

Product Description

The VALUE COLLECTION SC40605S is a 5-piece countersink set designed for deburring and countersinking operations in metal, wood, and composite materials. The set includes single-end countersinks machined from high-speed steel (HSS) with a bright, uncoated finish that provides a smooth cutting surface right out of the box. Head diameters range from 1/4 inch to 1 inch, and all tools feature a 3-flute, right-hand cutting geometry with a 60-degree included angle. Straight shanks ranging from 3/16 inch to 1/2 inch diameter allow these countersinks to seat securely in standard drill chucks and collet holders. The set stores in a fitted wood block for bench or toolbox organization.

This set is suited for machinists, fabricators, maintenance technicians, and skilled tradespeople who need a range of countersink sizes for flat-head fastener preparation and hole deburring. Applications include preparing bolt holes in steel plate, aluminum extrusions, and wood framing members. The graduated size range makes this set practical for job sites or shop environments where multiple fastener sizes are used in the same work session. No pilot is included, so these tools are run freehand or with a depth-stop collar.

Installation Notes

Install the countersink shank securely in the drill chuck or collet before operation and confirm the tool is fully seated and tightened. Power down the drill or press completely before changing tools or adjusting depth stops. Use appropriate speeds for the material being worked — harder metals require lower RPM to prevent premature tool wear. Eye protection and chip guards should be in place whenever countersinking operations are underway.
