Title: Great replacement chuck and key
Review: This is a great Jacobs Chuck for replacement on 1/2" drill. Comes complete with key and is bored to accommodate a locking screw to secure chuck on reversing drills. Easy to remove old chuck and install new by using a larger hex wrench in the chuck and tapping with a mallet.
