Overview:
The DEWALT Extreme 2 Metal Drill Bit DT5050-QZ is a 7.0 mm precision twist drill designed for clean, accurate holes in metal and other common materials. Made from high‐grade steel with a hard-wearing finish, it features a split point tip that helps start holes exactly where needed and reduces walking on smooth surfaces. Sized at 7.0 mm (0.28 in) diameter, it has a working length of 66 mm (2.6 in) and an overall length of 109 mm (4.3 in), making it suitable for general jobber-length tasks. It fits standard three‐jaw chucks on cordless and corded hand drills, as well as bench drill presses. The Extreme 2 design is well regarded by trades and DIY users for dependable performance on steel, alloyed and non‐alloyed metals, wood, and plastics.
Key Features:
