Value Collection SC10605S Countersink Set 5 Pc Hss

Product Description

The VALUE COLLECTION SC10605S is a 5-piece countersink set designed for deburring, chamfering, and countersinking operations in metal, wood, and composite materials. Each tool features a single-flute, right-hand cutting geometry with a 60-degree included angle, which produces clean, consistent countersunk seats for flat-head fasteners. The set covers head diameters from 0.25 inches to 1 inch, with straight shanks ranging from 0.25 to 0.5 inches in diameter. All five countersinks are manufactured from high-speed steel with a bright, uncoated finish. The set is stored in a wood block for organized bench access. Machinists, toolmakers, and general fabricators are the typical users of this type of set.

This countersink set is suited for job-shop and production environments where a range of countersink sizes is needed at one workstation. The single-flute design minimizes chatter and produces a smooth seat finish across a variety of workpiece materials. The included wood block keeps each tool indexed and ready for use at a drill press, lathe, or hand-held drill. The set is appropriate for countersinking screw clearance holes prior to fastener installation in both light manufacturing and maintenance-repair-overhaul applications.

Installation Notes

Secure the appropriate countersink in a drill chuck or drill press spindle, ensuring the shank is fully seated and the chuck is tightened before operation. Power down the machine and disconnect it from its power source before changing tools. Use appropriate cutting speeds for the workpiece material — lower speeds are recommended for harder metals. Eye protection and chip guards should be in place before cutting.
