  • This thing is awesome!
Size: For M12 34xx/Gen3 ONLY Color: Red Right Side
I absolutely love how the colors match the tool perfectly! All the magnets for the retention are very strong and I have seen no issues with anything falling out. I haven't thoroughly tested the outer magnet for screws and such but it seems pretty strong. The only problem I had was the included mounting screw. It seems to be either the wrong length, off by maybe a millimeter, or it's not exactly the right thread. It either bottomed out or bound up and the head snapped off. A perfect fit is 6/32 thread and 1/2 inch in length. Maybe my specific driver had a more shallow hole, I really don't know but with the new screw, works awesome! ... show more

  • Amazing little addition for your hex driver!
Size: For M12 34xx/Gen3 ONLY Color: Red Right Side
I could have gone with a 3D printed version, and I debated it. But for the price, you should go with the injection molded version. It feels much more premium and is super sturdy. The magnets are super strong and it installed perfectly onto my hex driver. The rubber surface is also great for holding the random couple screws you need in a pinch. 10/10 would buy again and probably will. ... show more

  • Great add on
Size: For M12 34xx/Gen3 ONLY Color: Black Right Side
Awesome bit holder. Only thing I wish was different is that it was sit back further because I use a 2 inch extension with a 1 inch bit and it gets in the way of what I’m screwing especially if it’s a deep item and I use the GEN three M12 impact so only thing I could say is that it gets in the way if you have a real long bit and it goes past to face, the impact in the three bit holders in the back are a little bit weak to drop. I’ve had all 3 one inch bits go flying out of the back other than that. It is an awesome tool and it keeps everything right there in your hand so you’re not carrying around a big bit box. You have everything right there ready to go when you are ready for your day of work I would recommend it to anybody that is looking for the solution like I was. ... show more

  • Decent
Size: For M12 34xx/Gen3 ONLY Color: Black Right Side
I still have it on my drill 2 years later. One magnet fell out. Sometimes bits fall out. Make sure to use locktight on the screw. Overall pretty good product

  • Perfect fit and high quality
Size: For M12 25xx/Gen2 ONLY Color: Red Right Side
I now have one for each side of my Milwaukee because the first one was just too good. The magnets inside are strong enough for my bits and my 1/4hex with a 10mm socket on it. Highly recommend these.

  • It’s a pretty nice bit holder.
Size: For M12 34xx/Gen3 ONLY Color: Red Right Side
I originally got it for my M12 drill but I quickly realized that my bits on the side that holds the longer bits protrudes past the adjusting clutch on the drill which gets in the way of adjusting it easily. I’m still able to turn it but it’s just not convenient, so I switched the bit holder to my M12 impact. It works way better on the impact because the adjustments are on the top of the impact driver. I realized I also have a lot more loose bits in my HVAC tool bag which is where I keep my impact so it was a great upgrade to easily access stuff during work. The bit holder feels of pretty good quality I think it’s a fair price to pay. The magnets inside of the holder for the bits are great, not too strong, not too weak, which makes removing of them and also securing them reliable. My only little complaint is that the magnet that holds screws seems a tiny bit weaker than I would like but it does hold them without dropping just doesn’t feel extremely strong. Also, be aware that filling up the bit holder can make the drill/impact more top heavy and takes a little getting used to. ... show more

  • << BE CAREFUL INSTALLING!! >> ||. This bit holder ruined my brand new M12 impact
Size: For M12 34xx/Gen3 ONLY Color: Red Right Side
Firstly, I've bought four of these and have them on three of my m12 drill/impacts. They are amazing, and my favorite bit attached bit holder, they are a joy to use, great design and well made.....mostly. I've put them on, taken them off, swapped them several times, lots of experience with them. Recently I had to replace my M12 impact and drill, so I purchased another 2 pack of the simon bit holders to install. Unfortunately as I was installing the holder on my impact the screw broke, leaving the post in the threaded insert. I hadn't even got the screw seated, it was not overtightened. Keep in mind the supplied screws have a dab of threadlock on them, which is great, if the screw stays in one piece. I tried to get a grip on it with a small set of pliers to back it out but there just wasn't enough sticking out. Next I tried screw extractors, again couldn't get a good bite on it. Tried to carefully drill out the post, but at last nothing worked. This is a BRAND NEW impact, I pulled it out of the box moments before installing the also brand new bit holder. I have others that are over a year old and have been on and off several times. Not sure if they are using different screws now or it could very well just be a bad one. Either way I now have a brand new impact with a ruined attachment point, didn't even get to use it yet. Super disappointing. BEWARE! Don't ruin your tools. I would like to message the seller directly but cant find their contact info. Hopefully it was just one bad screw. ... show more

The bit holder was a great fit to my m18 fuel driver the magnets are strong and the bits don't move or get lose from the holder when in use I have been a carpenter for over 40 years and supervisor of construction crews and this is the best I've found for convenience and ease ability to use I would approve this to all, great product. ... show more
