The Trend Snappy 5 Piece Drill Countersink Set is a comprehensive set of adjustable drill countersinks designed for creating clean, professional pilot holes and countersunk recesses in wood. Supplied with five sizes covering the most common wood screw gauges, this set is well suited to carpenters, joiners, and site contractors who need reliable, consistent results across a range of fixings. Each countersink is constructed from heat treated tool steel for durability, with an HSS drill bit to produce accurate pilot holes. The 1/4" hex shank is compatible with standard quick-release drill drivers, making bit changes fast and convenient on site or in the workshop. The countersinks are adjustable to accommodate different screw lengths, and can also produce a counterbored recess of either 9.5mm (3/8") or 12.7mm (1/2") in diameter — ideal for setting wooden plugs to achieve a clean, flush finish over fixings.
