Value Collection SC101009S 9 Pc Countersink Set Hss

Product Description

The VALUE COLLECTION SC101009S is a 9-piece countersink set designed for creating clean, conical recesses in metal, wood, and composite materials ahead of flat-head fastener installation. Each countersink features a single flute geometry with a 100-degree included angle and right-hand cutting direction, making it suited for general-purpose countersinking in a range of shop and field applications. The set covers head diameters from 3/16 inches to 1 inch, giving technicians and machinists the range needed to match common flat-head screw sizes without switching tool sets. All cutters are made from high-speed steel with a bright, uncoated finish.

This set is appropriate for use in metal fabrication shops, woodworking operations, electrical panel work, plumbing rough-in, and HVAC sheet metal applications where countersunk fasteners are required. The straight shank design accommodates standard drill chucks on benchtop drill presses, hand drills, and CNC machines. The included wooden storage block keeps all 9 countersinks organized and protected between uses, making it practical for both fixed shop installations and job-site tool carts.

Installation Notes

Countersinks are installed by trade professionals and machinists using standard drill presses or hand drills with a compatible chuck. Always secure the workpiece firmly before operation and set spindle speed appropriate to the material being cut. Inspect each cutter for chipping or wear before use and do not exceed the recommended depth for the fastener being seated. Follow applicable shop safety practices and relevant code requirements for the trade application involved.
