Lock-N-Load Quick-Change extension bars let you swap bits quick and easy with just one hand. The tip releases from the holder when you pull up the quick-lock on the holder. The ball-bearing hex jaw keeps the bit firmly in place. The housing and body are made of carbon steel, which boosts durability and extends the service life.
