Beautiful but needs better sizing

The beats are good but as others have said they are badly marked. You need perfect lighting or a magnifying glass to see them. I made a simple label, printed it out and taped it to my kit. Attached here for everyone to print out. Since I can't attach a PDF here, you'll probably have to resize it when you print it, but it works great if you have it.

Pros
  • Durability: Thanks to the unique drill design and durable black oxide coating, this set generates less friction and offers longer life than standard drills.
Cons
  • I don't remember

Not compatible with impact wrenches

Not as advertised. I bought these because the add-on showed they could work with The shock driver were compatible. They are not. One piece from the package turned out to be the correct size stem to attach to my driver. I think it is the one they showed in the photo. Completely misleading. I keep them as they are good standard beats but give two stars for misleading advertising and put my project aside for a while to get the beats I thought I ordered.

Pros
  • Reliable: Tri-Flat shank on bits 3 16" and larger for better grip and protection from possible slipping.
Cons
  • Not automatic

Expect the best from twist drills

I'm just not sure about this or that set of drills. Haven't had a chance to use them yet and if they hold up like my other Bosch set I'll add them to my review! I gave 2 stars because I don't know how good they are. I had a chance to use this set of drills yesterday and the bit I used did the job perfectly and I hope the others work just as well. Update on this drill bit set, these bits are not as good as I expected in my opinion. Used the next size up bit to enlarge the hole and the cutting…

Pros
  • Versatile: Versatile in drilling Designed for contractors, electricians and toolmakers who need accurate and reliable drills for versatile use.
Cons
  • So far so good
