1/2-20UNF Mount 1.5-13mm Capacity Key Drill Chuck for Air Impact Wrench Converter Conversion Tool with Chuck Key and 1/2 inch Socket Square Female Adapter

Not sure what to say but this worked for my needs. I modified an old radial arm saw into horizontal drill and this piece worked perfect for my need. Solid component and included everything described. No wobble and great value for the money.

Excellent and durable product. Works great! Fast shipment. Packed well. Thx!

Gets the job done but will wobble a bit when used on an impact driver not for precise work. I keep this with my dewalt 1/2" impact in case.

It was good, buying another one. Bought one in 11/2023 lasted till this past week. It worked pretty good for the price. Using this one a heavy duty Ryobi impact battery powered drill, tighten the chuck would give me some problems sometimes. It finally gave up and fell apart, due to the harsh impact vibrations. For the price I’m not mad. For occasional use, for a year and a half use, I’m investing my money in a second one with this seller. At least I know what I’m getting

The little screw inside broke on the first use.

I don’t think this is supposed to happen lol it’s cool I like it but I’ve tighten it down as much as I could and I guess all the torque from the gun just removes it idk

I was pleasantly surprised when I received this. For less than $18, I expected something of "cheap-ish" construction that might last me a few uses. That would have been fine, since I really only had one mission for this thing; drill a hole in the floor of a junk car - through standing water - with an 18" Rock Carbide bit using my new DeWalt DCF-899 Impact driver. However, the quality of the adapter is really good - helping me tear through that job with ease - and made me realize that I'll probably use this thing a LOT! I already have a corded drill, so it won't exactly help me replace that. This is mainly because the 1/4 coupler does have some movement where it joins the DeWalt (which I expected), and could make for some less than precise drilling. But 75% of the time, I just need to make a hole in something, not build furniture, so for that reason, I'm thrilled that I bought this. Super useful! My DeWalt has just become a cordless drill. Yes, the DCF-899 is heavy, so if you are putting in 200 deck screws, this may not be the best solution. But if you are looking to get some extra usefulness from your impact driver, I highly recommend the adapter. [It does come disassembled, which just means that you'll have to put in one screw to mount the 1/4" end to the drill portion. ]
