If you’re using M12 tools, this is a must-have accessory.
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.

Good product, lot of features, and matches the M12 driver perfectly!
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.

It’s a pretty nice bit holder.
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.

Expensive but probably worth it?
Way too expensive, but super useful and well made. Magnets ate good and it's made fro. Decent plastic and is molded well. Use it all the time. 4 stars cuz of the cost.

Get this! Wow!
I should have got this years ago! This is amazing! Makes my job a lot easier and faster. Perfect fit. It made up the cost in one day, I’d say. Well done, Simon Tools. Well done.

Increased functionality and reduced frustration
Ordered this because I got tired of playing musical bits on top of a ladder. Saw a guy on the job with one of these and thought it looked really cool. I ordered it for my M12 impact, I wanted something that wouldn't add weight or bulk; retaining a lightweight and compact tool was my goal not only for ergonomics but for storing in my tool bag. This bit holder is a little bulky but not to the point where it becomes a problem. The little magnet on the side was a really cool plus that I didn't know about. Already ordering another one for my other tools and my friends at work have ordered some as well. Great little utility to make life easier.

Magnets should be stronger
I love everything except the magnet strength. Stronger magenta should really have been used. Screws aren't held very securely, especially if there are multiple 2 or 3 inch screws.

عجبني التصميم الشكل الانسيابي. ثباته. كمية الاماكن وفيه ٣ اماكن عميقه للرؤوس الطويله و٣ قصار للرؤوس القصيرة .لكن فيه عيب ان المغناطيس اللي بالجنب ماهو قوي كفايه عادي ان البلوط تطيح مو ثابته بقوه

Great product
Excellent quality. Really nice. Fits well. Good magnet. I think it’s a lot better than the thing i had printed that was already almost broken. Plus this one will hold 6 bits. That’s cool. Plus the magnet for random stuff on the side. Awesome.
