DeWalt DT70755 Black & Gold HSS Drilling Set (21 Pieces)

The DeWalt DT70755 Black & Gold HSS Drilling Set (21 Pieces) is a premium metal drilling solution housed in a versatile ToughCase+ stackable case, designed for customisation and connectivity with other ToughCases and the TSTAK Caddy. Its modular design and clear lid offer convenient access and organisation, while the inner dovetail system allows users to rearrange components to suit their needs.

The drill bits are made from high-speed steel (HSS-G) for superior wear resistance and longer life, featuring ToughCore technology that boosts stability and reduces breakage when drilling deep or under side load. A speed tip ensures fast, accurate starts without walking, even on curved surfaces, and the anti-slip shank (5mm and above) prevents chuck slippage. This 21-piece set includes a wide range of metric sizes from 1mm to 12mm, making it ideal for metalworking tasks where precision and durability are key.
