This pack of 10 DeWalt Extreme 2 HSS-G metal drill bits features a 3.2mm diameter and a 65mm overall length with a 36mm working length. Designed for drilling thin sheet materials like steel, iron, nickel, brass, wood, and plastics, these drill bits offer faster drilling and better durability than standard HSS-R bits. The gold ferrous oxide coating prevents overheating for extended bit life, and the non-slip shank ensures stability. The metal tip starts drilling on contact for clean, accurate holes. Ideal for both professional tradesmen and DIY enthusiasts.
