1/2 in. 20-Drill Chuck and Key is rated 4.8 out of 5 by 4.
Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
