I'm a carpenter, these bits have lasted for well over 6bmonths of brutal daily use, from boat docks, to 5 decks and four different remodels. I've lost some, stripped some, but overall they are the absolute best bang for your buck in regards to not wanting cheap stuff, but not shelling out 40 dollars for a some other brand of bits.

I've abused the Philips bits and they're hanging in there. The extended bits are a nice touch. Easily magnetized, if that's your preference. It is mine.

Well-thought out case provide some easy access to organized bits. I like the latch because it doesn’t challenge me every time I’m trying to open it. It just does its job and helps me do mine better. I especially like the array of longer bits. They’re my go to bits every time for torx and Robertson (square drive), the two I use most.

I purchased this set about a month ago from Lowe's but I have been using those impact bits from Bosch before and they are frankly hard to beat. If you care about the storage box I think you will love it, too. The clip may not be the best, but otherwise the quality and ergonomics are excellent. It is so easy to take the bits out and put them back in - just remember to tilt them before (see the picture). And they never fall out on their own, even if you drop the box! Bottom line is they do their job very well and should last long. These particular ones are manufactured in Vietnam, if you care for these things.
Would've been nice to include a 5/16" nut driver as I've noticed most nut-head screws are either 1/4 or 5/16. Other than that, good set at a good Father's Day price.
I love this set as it has a great assortment of bits for almost every job I need to tackle. The spacing of the bits and each row has decent spacing so you can easily remove and reinsert them in the case. The case also seems pretty sturdy and I've dropped mine a few times and it can survive some falls without all the bits flying everywhere. What I don't like about the set is the plastic clasp thing sometimes has a tendency to fall open by itself. What I would prefer compared to this one and newer models is I'd prefer the plastic to be translucent. It's always nice to be able to see what's inside your bit set when you've got a fair amount of them to choose from.The bits themselves seem to be of better quality than some of the other manufactures.

I haven't had any of these bits fail on me yet compared to others that sometimes will splinter and shatter with my impacts. These were on clearance so they were a great value compared to even buying them with the individual sets of them. They're also a better value than my of the options from other manufactures and I just like this assortment much better as it offers a great variety.
I'm loving this case! It lets you easily pop out a section to better select the bits that you want, which is good for my big, clumsy fingers. I also like how rugged it is because I have dropped it more than once with no damage shown at all. I just knew that the lid was going to break off and pieces would go everywhere. But it holds up extremely well. You really can't go wrong with this set, so buy it and you won't look back!
What does "10x longer" mean? What is their maximum (breaking) torque rating? Bosch does not say and they do not clarify what “10x longer life” actually means. But despite this lack of information, I really like this set.I have not used them with an impact driver and cannot attest to their "10x toughness". The bits do grip the fastener (especially Philips) fairly well and seem to be less prone to slipping than the traditional "gray" bits I have. These Bosch bits also work well in my favorite ¼” bit screwdriver too.The 44-piece set (SDMS44) has multiples of the most common size bits [Philips (PH), Torx (T), and Square (R)], plus a quick-release sleeve. There are even two #2Square Philips (PHR2)…interesting.Size markings are easy to read (when new); however, with ... MoreWhat does "10x longer" mean? What is their maximum (breaking) torque rating?

Each of the red bit holders (inside) are removable allowing you to take bits/bit sleeves with you w/o taking the hole case OR it will allow you to swap out bits/holders to allow a more customizable set. The case can hold up to 8 rows of standard size bits; less if you incorporate longer bits.The case even has provisions for 4 extra bits on the latch side, presumable for tasks requiring frequent changes. These spots only offer a friction hold for quick in/out use. The case will close with standard size bits in these spaces in case you need extra (4) bits to augment what is already there.Overall, I am very satisfied with this bit set and it should provide many years of use. I would recommend it and/or the other sets in this Bosch Impact bit family.
What's great about this set is that each bit is labelled and appears to be laser etched. There are some bits of the same size, which is nice as heavily used bits wear out. These are really strong, iron oxide coated, and fit easily in both a Bosch and Worx electric screw driver/drill. The case is pretty compact compared to similar bit sets with rubber exterior edges that will not slip while placed on a ladder or other surface. The bits snap into place and are nicely organized within the case. This set has really come in handy around the house for many jobs.
This compact kit has a wide variety of bits. Perfect for people who work in plants with alot of different machinery, with alot of distance to cover between work areas.
