    • extensive quality set at a good price
Model: MS4091
Great comprehensive set of bits and drills. Really like the hand bit holder as accessory. Push the drills out before taking them out to keep your fingers safe.

    • Great product. :)
Model: MS4091C
Absolutely fantastic. It has anything and everything you need to do any carpentry. I was very impressed even with the bits, they're holding up still! 6 months later. Ish. There are shank bits and regular bits so drill accuracy is no concern. Great fit. Good value for the quality. :) I promise.

    • Solid quality, frustrating organization
Model: MS4091C
This is pretty much what you’d expect from Bosch: well-made, professional, and cleanly executed. The bits themselves are good quality, perform as they should, and I have zero complaints about how they actually work. Where this set falls down is organization and usability. Bit layout makes quick use harder than it should be The drill bits are laid out logically by material and size, which is great. The problem is with the driver bits. Phillips, Torx, and other bits feel oddly scattered throughout the case instead of being grouped in a way that makes quick selection intuitive. It comes across less like thoughtful organization and more like everything was arranged simply to fit as tightly as possible. On top of that, the bit holders are very tight, and so are the slots they sit in. Either one on its own would be fine, but having both makes grabbing and returning bits slower than it should be — especially if you’re trying to work efficiently and keep things organized. Ironically, despite how tight everything fits, several bits were loose in the case when I opened it, likely from shipping. So it’s tight when you’re using it, but not tight enough to prevent movement in transit. Good features, limited variety The magnetic bit holder is a nice inclusion and works well. The case itself is also solid — durable, well-built, and the latches close securely. That said, while this set covers the basics, it doesn’t include every size or variation you might want. That’s not unexpected for a combo drill/driver kit, but if you’re used to larger driver-only sets with extensive bit options, this will feel a bit limited by comparison. Final thoughts This is a high-quality bit set with good performance and a durable case. If you value Bosch build quality and want a compact, professional kit, it delivers. Just don’t expect fast, intuitive access to bits — the organization and tight tolerances slow things down more than they should. 4 stars because of its excellent quality and durability, held back by awkward organization and overly tight bit retention. ... show more

Versatile kit that support most of the uses for power drills. I have many smaller kits containing special boys, but this replaces most of them in a convenient SINGLE package.
