great bits [Posted on 2006-02-01]
the bits are great and go through anything, though i wish the case would fit into the drill's carrying case. in any event the bits are excellent.
I prefer the DeWalt bits [Posted on 2006-04-11]
I first because very impressed with cobalt bits after drilling a ton of holes in 1/4 red iron with dewalt bits and the bosch just don't last nearly as long. without a pilot hole the bits above 3/16" wear out much faster than the dewalts. It's the nicest case for drill bits i've ever had though so it gets' three stars, when one brakes or wears out, i just replace it with a dewalt...
Bosch Cobalt Drill Bit Set [Posted on 2006-08-18]
I purchased these bits as cobalt is better/stronger than titanium, and therefore should last longer. One bit was missing from the set. I called Bosch and they immediately send me a replacement.
Great Drill [Posted on 2007-02-23]
It is a good-solid drill. A little on the big side, but still a good product.
very high quality [Posted on 2008-09-21]
these are very high quality bits, they are sharp and they stay sharp. I notice they have a very steep angle to them which means that they attack he material rather rapidly.
