- Reviewed in the United States on June 14, 2021Style: 41pcVerified PurchaseBosch has always been the hallmark of high quality, and this drill bit set is no different.
(All us VW fans from way back remember Bosch parts as the "go to" parts replacements. When I recently saw that they had introduced some battery operated drivers and drill bit set combos, my first thought was that it was probably high quality, solid, and soundly manufactured, and that I would not be disappointed with the purchase. Just like then, so now - pay a premium price but avoid a lot of trouble down the line!
And indeed these bits are high quality. Easy to remove, decent enough value for the money - (you're paying for the brand, and in this case, the brand holds up to its reputation very well!) (At least in my experience so far!) and sure to last a long time. These are the bits that you keep and re-sharpen when they get dull.
I've thoroughly enjoyed using these bits, well, as much as one can enjoy using drill bits - they really bite - the wood that is - and work as they're supposed to. Kind of took me by surprise in a way, having been used to bearing a lot of pressure on the drill, but these went in like a hot knife though butter. Good drill bits can make a big difference.
I also noticed that the metals seem to be stronger than some other bit sets I've purchased for less elsewhere. You can tell just by looking at the metal and seeing the machining and feeling the edge. (Make sure to have a bandage handy if you do feel the edges - - - they're sharp!)
I would heartily recommend this bit set as an addition to the Bosch battery operated drill and impact driver set, or even as a "stand-alone" for someone who already has a favorite drill.
In my opinion, these bits live up to their name and implied quality of the brand.
And that's not all - the bits come packed in a very usable plastic case with bit holders that are actually easy to remove the bits from and put back into. Yeah, this helps keep things organized. No cheap case either, seems to be strong and durable and should last as a bit holder for many years to come.
Nice deal all in all - totally recommend - good quality for the money and a brand name to boot! No doubt they will last for years!
- Reviewed in the United States on February 22, 2024Style: 91pcVerified Purchasethis set truly has everything I need for various applications in wood, metal, and masonry. The included case keeps everything neatly organized, which is a huge plus for me. It's incredibly handy to have everything in one place, saving me time and effort when tackling projects. Plus, the value for money is exceptional – this set provides excellent quality at an affordable price point 30$ for 91 pieces.
While the drill quality could be improved for longevity, I still find this set to be a fantastic investment. Overall, I highly recommend the BOSCH MS4091 set to anyone in need of a comprehensive drilling and driving solution. It's reliable, convenient, and offers great value for money!
