7pcs Hex Head Allen Bit Set 100mm/4 inch Long Metric H2-H8 Quick Release Shank Magnetic Professional Screwdriver Bit Set Perfect for Production Workshop

Used daily, hold up perfect!

These work great in tight spaces where a long t-handle won't fit, but need longer than average allen wrench. Ball helps with awkward angles.

Awesome set of tools! Fit my hex drill perfect and love the extended reach on them and that they come in a little holder so you dont lose them also a Very good quality set and fast shipping too!

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.

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.

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

Surprised at the quality of these, used everyday on the job, great for putting together furniture. Length and attachment are ideal for many applications

Ok bits

Good product, good seller
