The Sealey 6 Piece Hex Shank Tapping Drill Bit Set covers thread sizes M3 to M10, providing the correct pilot hole diameter for each tap size in a single, organised set. Designed for use with power drills and electric screwdrivers, the hex shank design ensures a secure, slip-free grip in standard quick-release chucks — eliminating the frustration of round-shank slippage during drilling. This makes the set well suited to metalworking tasks where precise, clean pilot holes are essential before threading. The set is ideal for engineers, fabricators, and maintenance tradespeople who regularly cut metric threads in steel, aluminium, and similar materials. Having the matched drill sizes for M3, M4, M5, M6, M8, and M10 taps to hand removes guesswork and reduces the risk of tap breakage caused by undersized pilot holes.
