Rated 4.9 out of 5 by 9 reviewers.
Rated 5 out of 5 by Milwaukee 3/8 in. Square x 1/4 in. Hex Shockwave Impact Adaptor This item works very well. I think it should have been included in the M18 Fuel 18-Volt Brushless Lithium-Ion 3/8 in. Impact Wrench. There is even a spot in the case for it to fit. It is not stocked at Home Depot. I had to order online. December 10, 2013
Rated 5 out of 5 by Turns 3/8 impact wrench to impact driver! I just got it so can't tell you the longevity of it but it seems very good quality, I expect it to last. I attach it to my Milwaukee 3/8 impact wrench with friction ring and it holds on pretty well, like others have said it does have a little wobble to it, but when driving screws, you're applying pressure so it wont wobble anymore. $15 for this vs $130 for an impact driver, plus this is a lot stronger. You decide. May 24, 2013
Rated 5 out of 5 What a money saver!!!... WOOT! WOOT!!!... This amazing adapter saved me the hassle of purchasing a drill... It easily converted my 450ft.lbs. Cordless Impact Wrench, into an awesome drill... brushed area on the adapter tends to slightly rust, but not a big deal... September 23, 2014
Rated 5 out of 5 by This product has great features Good features I can use on 3/8 to 1/4 drive bits,quick release December 20, 2013
Rated 5 out of 5 by Great upgade for a 3/8" impact driver This adapter allows the use of 1/4" hex bits. The problem I had in the past was my old impact (18v Dewalt hex driver) breaking the hex to 3/8 adapter. My new impact is a Dewalt 18v 3/8" sq. So with the Milwaukee adapter I can still use all my 1/4" hex bits. September 18, 2012
