Drill Bit Extensions
Extend your drill bits and get into hard-to-reach places with our large selection of drill extenders. They let you use threaded bits, countersinks, and more with a regular drill chuck.
Every combination for use on aircraft in stock
At Yardstore, we have in stock every length and end type you will need. Get threaded, dual-threaded, and non-threaded drill bit extensions. Extend standard drill chucks, quick-change drills, and angle drills.
Save with kits
As an option instead of buying common lengths individually, purchase in 3-piece sets for a savings:
Dual-threaded extensions (male on one end; female on the other)
