Dewalt DW2535 Countersink Set 3 Pc 4 Flute High-speed Steel

Product Description

The DEWALT DW2535 is a 3-piece combination drill and countersink set built for trade professionals who need fast, repeatable countersinking in wood, composite, and light-metal applications. Each bit features a 4-flute design with a straight 0.25 inch shank compatible with the Rapid Load quick-change system, allowing tool-free bit swaps in cordless and corded drivers. The set covers a head diameter range from 0.125 inches up to 0.19 inches and an included angle range of 77 to 83 degrees, making it suited for standard flathead screw seating. Bits are manufactured from high-speed steel with a bright, uncoated finish and a maximum overall length of 6 inches.

This set is designed for carpentry, cabinetry, decking, and general fastening work where pre-drilling and countersinking must be done in a single pass. The Rapid Load shank system makes it a natural fit for DEWALT quick-change driver setups on residential and light commercial job sites. Woodworkers, finish carpenters, and general contractors commonly reach for this set when installing flathead screws flush or below a work surface. Right-hand cutting direction is standard for all three bits in the set.

Installation Notes

Installation of combination drill and countersink bits is performed by woodworkers, carpenters, and general tradespeople using cordless or corded drills and drivers. Secure the 0.25 inch straight shank firmly in the chuck or quick-change collet before operation. Set drill speed appropriate to material hardness and bit diameter to avoid overheating the high-speed steel cutting edges. Inspect cutting flutes for wear or chipping before each use and replace bits that show signs of dulling to maintain clean, accurate countersink seats.
