So you've got a diamond core bit with a 5/8" thread but your drill only takes 1/2" chucks?
No problem—this Delta Diamond adapter is exactly what you need.
It lets you run bigger core bits on a standard 1/2" drill without any fuss, so you don't have to buy a whole new drill just for one job.
The hex shank locks into your chuck nice and tight, so no slipping or wobbling while you work.


Whether you're a contractor, a plumber, or just a DIYer tackling a home project, this little adapter is a total lifesaver.
