Brand new Heavy Duty 3/4 key less drill chuck for Shopsmith MARK V 500
This chuck is a large size real drill press key less chuck. Not one of those half plastic Jacobs hand drill chucks screwed onto a buffing wheel arbor those others are selling on Ebay. No more slipping drill bits. Large jaws tightens on bits with little effort.
