This magnetic bit holder has quickly become one of my go-to accessories for my Milwaukee M12 tools. The magnet is strong enough to hold bits securely during heavy-duty tasks, but not so strong that swapping bits is a hassle. It feels durable and well-made, with a solid metal construction that stands up to frequent use. Using it has made my work much faster — no more dropped or lost screws, and the holder keeps everything right where I need it. It’s compact, easy to handle, and fits perfectly with the M12 drivers.

The media could not be loaded. So far very stoked on this bit holder/magnet! Actually quite impressed with the magnets. They are even holding the double sided bits quite well which I like to keep on my M12 as it's my go to for quick fixes that I leave in my truck at all times. You can see in the video I can't even shake them out despite not having a full hex head contacting the magnets. I also love the side magnet I put about a dozen 1.5" deck screws on there while disassembling something and didn't lose one! It's quite low profile and hasn't really gotten in the way at all. Time will tell how well it holds up but so far I gotta give it five stars. One note below about an issue that may or may not be resolved yet between Amazon and the seller. I had a bit of trouble getting the right model for my Gen3 M12 impact driver due some issues with Amazon mis labeling some of the stock. Just be careful if you order the BLACK Gen3 M12 for RIGHT side you may get the wrong one instead you may get the one for Gen2 which won't work on a Gen3 driver. I went back and forth with Amazon doing a return and getting the wrong one again despite sending a message to make sure they sent the Gen3. After this they promised me it would be ok, it's fixed, go ahead and order again. Well again it was the wrong one sent. I returned the third one and had given up, but then got to talk to Simon the owner, and he straightened everything out for me. I ended up going with the Red which was not having issues with fulfillment and I'm actually really pleased with how well it matches the red driver.

I definitely consider this an upgrade to my impact as well as my hammer drill. I’ve got a combo of this unit on one side then the magnetic bit holder (also from Simon tools) on the other side. Super useful combination, six bits should cover most things I encounter on the one side, then screws and drill bits on the other side (see pic). The plastic construction on the unit is pretty tough with a rubberized magnetic section (magnet is little weak). The rubber magnetic patch will hold a number of loose screws as well. The magnets in the slots are very strong, no worries about tips coming out. I really love not having to grab a box of tips when I need my drill for something. I keep a couple of adapters, Phillips, and a torx bit in there.. maybe a slotted. It’s become one of those tools you can’t imagine not having. Just an extension of the drill. I read where someone wrote that the drill becomes top heavy. I haven’t had that issue myself and I thought I would. The drills having remained fairly balanced. Full disclosure I am using the larger bottom batteries, 3.0 and higher I believe.. that helps balance the drill. I’m a new fan of Simon Tools!

I was able to use my knife to make them fit my M12 Milwaukee. I even made sure that the model number matched the fitment, still not perfect. As others have stated, they're a good add on, but be prepared to modify it. If you want a perfect fit, do not buy. I also had to drill the mount holes a little larger and find better screws long enough to use. On the plus side, it's nice to have the bit with the unit, and I bought one for each sideand the bits can be in the back or front, on both ends.

This went on my Milwaukee 12 V impact gun perfectly no more digging around in my pocket for a spare bit. This is able to keep my three main bits along with the one that's in the impact gun as well, so ability to rotate and keep the work going is great highly recommend this would like to add it to every single drill and impact on that I own.

It fit perfectly to my new Milwaukee surge drill. I like this one because it screws into an existing threaded spot on my drill. No sticky pads or Velcro or any nonsense. Nice clean fit holds just enough bits so I don’t always have to go running back to my little tool kit if I need to change out a bit real quick. It fits really tight to the drill so you don’t have to worry about getting into tight spaces still. It’s an awesome addition to a perfect tool for me.

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.
