This 2.5 x 57mm drill bit from DeWalt has been manufactured to a very high standard courtesy of the innovative tapered web which greatly reduces breakage, while the gold ferrous oxide coating prevents overheating for longer bit life. Whether you are a professional tradesman or DIY enthusiast, the drill bit is ideal for portable drilling of steel, alloyed and non-alloyed up to 900N/mm², and for drilling a sheet or thin materials (suitable for use in wood and plastics).
