Not sure this is right place but worth a warning if you have an expensive paint job. Got a brand new one to work on my AD. First use, bit came loose, drill slipped and scratched my door paint. Figured it was me and my old arms. Tried it again on the bench and it did it EVERY TIME !! Looked on net and not alone with dozens on complaints about defective/dangerous chucks. Taking it back to Home Depot.
