Hi, Has anyone tried this with a hand impact driver (the type you hold and strike with a hammer)?

Asked by Jim April 21, 2020

Answer

no i have not but it works really good with a 3/8 impact driver

Is compatible with dewalt 3/8 impact drive

I often use mine on my Dewalt 3/8 impact wrench rather than carry a separate impact driver, and even occasionally with my pneumatic impacts in the shop for more speed and power. No problems so far. It's a nice sturdy adapter.

Is this in store ? Penfield , NY location panorama trail.

Answers

Late answer, but no. This adapter only works on 3/8 wrenches. You must have a socket for this adapter to fit.

Does this adapter have any kind of means to keep it secured to my impact

Asked by Rich July 20, 2016

Just take a screwdriver to spread the O ring on the anvil just a smidge. It'll stay on nicely.

Yes. Anything with a 3/8 drive.

Will this work with a 3/8" Ratchet?

Asked by Phillip December 30, 2014

Answers

should work with 3/8 ratchet, kind of overkill at that point though, this is made for an impact wrench so you can use it like an impact driver.

The Milwaukee 3/8 in. Square to 1/4 hex adapter is a great purchase. It allows the use of drill bits on an impact wrench giving you a variety of more options when using your impact wrench. The quality is fantastic, I haven't had any issues with it, and seems to be quite sturdy. It's magnetised, and has a locking mechanism to ensure the bit doesn't come out when in use. This little adapter saved me from having to buy an impact driver. Now that I have this I have both a driver and wrench.

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.

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.

I've only had the part for a few weeks and the spring that goes up and down to lock the bits in is coming out of the top so the pieces don't lock in properly anymore. Stays stuck open. Probably going to have to buy another one and a couple weeks probably not this brand if this is the way they're built.
