IRWIN 62116 12" Aircraft Extension HSS Fractional Straight 1/4" Shank Drill Bits with 135˚ Split Point

Tackle extended-reach drilling tasks with confidence using the IRWIN Tools 62116 aircraft extension drill bit. This 12in extension drill bit is engineered for installers who need reliable access behind panels, inside conduit runs, and around camera mounts—common requirements in security, surveillance, and low-voltage monitoring projects. Constructed from M-2 high-speed steel with a black oxide finish, the bit stands up to heat and resists corrosion while cutting through metal, wood, and plastic. The 135° split-point tip ensures immediate bite and eliminates walking, so holes start true and fast. A straight 1/4in shank provides compatibility with standard chucks and extension holders for seamless tool changes on-site. While optimized for extended reach rather than deep-bore drilling, this IRWIN 62116 bit delivers consistent chip evacuation and long life for routine installation and maintenance tasks. Add this aircraft extension drill bit to your toolkit to speed camera installations, secure mounting brackets, and run cable pathways—order now to improve efficiency on your next security or surveillance job.
