This Vise Grip 12-inch aircraft extension drill bit features a 1/2" fractional straight shank and is constructed from high speed steel with a fully polished black finish for extended bit life and precision performance. The tip is heat treated to create a harder, longer-wearing point, making it ideal for deep-reach drilling applications in metal and other materials.
Designed for use in aircraft and industrial MRO applications where extended reach is required, the straight shank ensures compatibility with standard drill chucks. The durable HSS construction and protective black oxide finish resist corrosion and reduce friction for reliable, high-speed operation.
