Value Collection SC40905S Countersink Set 5 Pc Hss

Product Description

The VALUE COLLECTION SC40905S is a 5-piece countersink set designed for right-hand cutting in metal, wood, and composite materials. Each countersink features a 3-flute, single-end design with a 90-degree included angle and a 45-degree centerline angle. Head diameters range from 1/4 inch to 1 inch, covering the most common fastener sizes encountered in fabrication, assembly, and maintenance work. The tools are machined from high-speed steel with a bright, uncoated finish. The set is stored in a wood block that keeps each piece organized and protected between uses. Machinists, tool-and-die workers, maintenance technicians, and general fabricators are the primary users.

This countersink set is suited for countersinking screw and bolt holes in both light production and bench work environments. The straight shank design is compatible with standard drill press chucks and hand-held power drills. The five-piece range allows the user to match the countersink diameter to a wide variety of flat-head fastener sizes without changing tool types. No pilot is included, so the operator controls centering through setup and workholding. The set is appropriate for general countersinking applications in residential and light commercial trade work, including HVAC equipment fabrication, panel work, and electrical enclosure assembly.

Installation Notes

Install countersinks in a drill press or hand-held power drill with the chuck securely tightened on the straight shank. Power down and de-energize any equipment being drilled before beginning work. Use appropriate workholding to prevent movement during cutting, and select the correct head diameter to match the fastener being seated. Replace any countersink showing signs of chipping or excessive wear to maintain hole quality.
