The DEWALT Extreme 2 Metal Drill Bit is a high-quality HSS-G drill bit designed for precise, burr-free drilling in thin-walled materials such as sheet metal, profiles, pipes, wood, and plastics. Its patented split pilot point helps prevent walking on contact, while an innovative tapered web reduces breakage. The gold ferrous oxide coating aids in overheating prevention, and the bit is suitable for drilling hardened and unhardened steels up to 900 N/mm² tensile strength. Key dimensions include a tip diameter of 4.2 mm, an overall length of 75 mm, and a working length of 43 mm, with a cylindrical shank of 4.2 mm. Pack quantity is 1.

Usage and specifications

Compatible with standard drill chucks with a minimum diameter of 5.0 mm and suitable for use in drill presses and handheld drills. It can be used for portable or stationary drilling of steel (alloyed and non-alloyed) up to 900 N/mm², with particular effectiveness on sheet or thin materials where accurate, burr-free holes are required. It is also effective in wood and plastic materials. The design features include a patented split pilot point to prevent walking/slipping on contact, an innovative tapered web to greatly reduce breakage, and permanent size markings located above the shank for easy identification.
