  • Well constructed
This is a great product. Very solid and well constructed and should last a lifetime...I can't imagine ever breaking this. The snap-collar 1/4 retainer holds bits securely. It is pretty big, but I purchased this to enable me to run drywall screws with my Hitachi 3/8 drive impact wrench, so fitting it into tight spaces is not much of an issue to me. I'm also not sure how you could make it that much smaller, as you have to leave room for the 3/8 drive shank, as well as the shank on the 1/4-inch bit. The 3/8 drive on this tool is definitely designed to work with a ball-detent type retention system. My impact uses a friction ring retainer, and it is slightly difficult to get on and off. This also causes the adapter to sit on the tool a little sloppily, but not so much so that it causes me any problems driving screws. I wish Milwaukee made a friction-ring version of this tool in addition to the ball-detent type, but it's really not that big of a deal. This is the only downside that I have seen with this tool, and I consider it to be a problem with how I am using it rather than the design itself. 5 stars! ... show more

  • High Quality Tool
I bought this to go along with my DeWalt cordless impact tool, I chose the square drive version impact wrench so that I could use it with sockets. You can use the 1/4 inch hex version of the impact tool with sockets but you need an adapter which will take a lot of the power out of the impact wrench. This adapter works perfectly and is very well made, feels solid. I like it so much that I also ordered the 1/2" square version as well. I have to admit that I haven't used any other brands of these but I believe they are of excellent quality and not too big as to cause clearance problems. The release mechanism works every time and I would highly recommend these. ... show more

  • I use it everyday at work
I love this adapter, it works great! The only downside I see is that if I put my drill face-down into a pipe or some other holder, I run the risk of the adapter being bumped and dropping my bit into the pipe (yes this actually happened). I’d prefer to pull outward to change bits, but oh well. Also it sometimes comes off the 3/8” square shaft. There are tiny holes on the adapter, and it seems as though you could tap them and add a set screw. They should’ve done that at the factory in my opinion. Other than that, I have no complaints it works as intended. Mechanism seems solid and doesn’t jam up. ... show more

  • Great tool
If you're going to use one driver for both 3/8" drive and hex bits, this is the way to go! My 3/8" impact driver is super useful, versatile, lots of socket/bit options, strong (just think the 3/8" square shaft is bigger/more solid compared to the 1/4" hex shaft), AND this adapter makes it so easy to quickly swap out for hex bits. ... show more

  • Updating review
I originally gave a 1 star soley for the reason it didn't arrive. After a couple delays it finally got here. The package looked like it went thru a war, but intact. So, that was not a problem. Instead of 2 or 3 days, it took over 2 weeks. Still it's here. Haven't got to use it yet. That is why I only gave it 4 stars. It feels solid. Not loose on the tool. It does feel well made. So....we'll see. Just wanted to go ahead and update the originak 1 star. ... show more

  • Really like this addition to my impact wrench
Great product looks very well made. A little odd in how it locks in the bit. I believe you pull the outside of the chuck away from tool to open and insert. I’m used to most others you push in to open/insert. Not issue it holds bits very well.

  • Works great, even on my snapon 3/8 impact.
Bought this when my hex impact driver was stolen out of my truck. I have a 3/8" snap-on impact that I figured I could use until I replaced the one stolen. This worked perfect. My snap-on is significantly more powerful than any hex impact driver, and it's not variable speed really at all, so it was a bit difficult in my situation, but this tool held up great. Although two guys in my shop swore I would break it soon. They say they had went through 2 of these and stopped buying them... but several months later, with significant use, this has held up very well. ... show more
