Rated 4.8 out of 5 by 4 reviewers.
Rated 4.0 out of 5.0 by Fits DEWALT Model # DWD110 3/8 in. Pistol Grip Drill Bought this to replace the keyless chuck (which broke after about 1 year) for my DEWALT Model # DWD110 3/8 in. Pistol Grip Drill. DeWalt wanted $45 for a replacement chuck for a $60 drill, bought this for $15. Works fine so far. June 12, 2014
Rated 5.0 out of 5.0 by Good Product for the price. The drill chuck was easy to install and fit the accessory shaft on my radial arm saw. I can now use my arm saw as drill press and horizontal drill. October 21, 2014
Rated 5.0 out of 5.0 by It works My Hammer Drill chuck finally wore out after years of service. I didn't want to buy a new hammer drill so I took it to the Home Depot here in Florence, Alabama to see what could be done to fix my problem. Truthfully, I don't know how long this chuck will last, but so far it has done the job. Drilling pilot holes in concrete, the bit held and that's what you want. September 23, 2014
Rated 5.0 out of 5.0 by RYOBI CHUCK Works well.Thought I would have to spend a lot more for a good one.I put this on a Craftsman 3/8 drill. to replace a bad keyless chuck and upgrade tool to a 1/2 keyed type chuck,which I always prefer on a electric drill any way. December 29, 2013
