Review: Got my drill working again - Chuck on my Makita died and wouldn’t grab bits. Inexpensive full metal replacement and works well.
Review: Worth the money - I replaced the chuck and key on my old DeWalt DW511 1/2" hammer drill with this. Fits perfect . Haven't used it for any hammer drilling yet. Chuck holds bits tight. Seems like it is made very well. Hardest part about the switch out was getting Torx out of the old drill. All in All pleased.
