DeWALT 3/8 in. Cobalt Drill Bit

Built for maximum speed and extended durability, the DeWALT 3/8 in. Cobalt Drill Bit powers through tough materials such as stainless steel and heavy metal with ease. Engineered with heavy-duty cobalt alloy steel construction, it delivers up to 4X longer life compared to standard drill bits when operating in demanding conditions. This high-performance drill bit features an advanced point design that starts immediately on contact to eliminate bit walking and ensure clean, accurate holes. The mechanically deformed spiral shank is heat-treated to resist bending and reduce lock-up during breakthrough, providing smooth operation across industrial and shop applications.
