5pcs Hex Head Allen Bit Set 150mm/6 inch Long Metric H3-H8 Quick Release Shank Magnetic Professional Screwdriver Bit Set Perfect for Production Workshop

Bought these almost seven months ago to use daily at my manufacturing job. Finally snapped the tip of my 3mm this morning because I blasted a fastener in the wrong direction while my drill torque was at max. Durability for money is great. I use my tools professionally for industrial machine building. They held up great as far as I am concerned. Ordering a second pack now.

Used daily, hold up perfect!

These are great i use them almost daily and definitely recommend them if you are looking for some longer bits for your projects

Overall, this is a good bit set and very helpful for getting fasteners in/out of tight spots. Quick release is great for fast changing bits on the go.Magnetized bits are always a plus too. Good tool for the price.Lost a star for 2 reasons:1.) After 3 days of heavy use and switching back and forth between the 2mm (H2) and 4mm (H4) bits, I found that the ends were beginning to round out despite the fact they never spun out.2.) The bits frequently locked into the fasteners when unscrewing. This could be good or bad depending on how you look at. I found this odd because you're mos likely to see this working with fasteners tightened to high torque specs, that have fitment issues (cross threading), or there are very lower tolerances. In my case, these were standard fasteners driven to 2.5 Nm and 4 Nm static, respectively. It was a little frustrating to have to work to get the fastener off the tool each time and made me a little concerned with the overall durability.That said, this is a good all around bit set for the price and it certainly got the job done. Other than having to spend a few extra seconds prying screws off the bits they were exactly what I needed for the job. Far faster than using a T-handle and other jobs that a standard 1 inch bit couldn't reach.I would recommend this tool for your workshop but I would not call it "Professional Grade" and I certainly wouldn't use it in production or on an assembly line.Just my opinion of course. But I hope it helps you make a decision.

So far so good. They really are magnetic, which can be useful in tight spaces. I only use the 4 & 5 mm, so can’t speak how long the others will hold up, but the handful of times I’ve used the 4 & 5 the quality appears to be there. Only down side, the fall out of the holder, had one fall sraight through the bottom the other day, but luckily I noticed so it didn’t get left behind. If you use a tool bag and not a box, you’ll definitely want to keep them in a canvas bag or something

Works perfect. Needed a bit set for my rc car and none worked as good as these ones.

Simply stating, these are cheap. They work ok but, are not high quality. I've used these for about a week and you can see the ends are starting to round. To be fair, I'm using these with a 12 volt Milwaukee impact driver. I'm a industrial machine mechanic. I'll probably replace these within a month. In a pinch, I might buy these again but, most likely not.

Ok bits
