Brittle, Bent and Expensive [Posted on 2005-01-20]
This is an expensive set of drill bits, and indicated that they were of a high quality, but as it turns out I am not overly impressed. First I found the smaller bits extremely easy to snap, sure you have to be careful with smaller bits... but these broke easily. Then some others were just fine. The metal index box is almost as important to me as the bits since it is what allows me to make the correct selection in a fast and timely manner, as well as protecting the bits when not in use and allowing me to get the right bit back into the proper place for use next time.
While the sizing is fine, the box itself is nothing to get excited about, and if you drop it once count on the racks flying out of the box all over the shop floor. Again... something that would not be a big deal... but this is the top of the line and I thought I would get a little bit better box.
The final straw was when I used the 1/2" bit, the largest in the set and I was needing an extremely precise hole... and I didn't get it (seating a bearing) I took the bit out and it rolled across my tablesaw top and was as crooked as can be.
This was NOT caused by any fall, drop, or misuse. It was the first time I had used it, I was drilling into soft plastic, and this is a 1/2" piece of steel/titanium. I couldn't bend if I tried. I wish I could say that this was a good set, some of the bits ARE good, but no way I can say that it is worth the price. You might be able to overlook a problem here and there.. but not when you are buying for the very best you can get.
Have to Agree with Previous Review [Posted on 2006-02-06]
I am a happy Bosch tool owner. Most of my power tool purchases have been Bosch as I replace my aging Craftsman tools. I have been very pleased with all of my Bosch tools so went looking for Bosch bits when I shopped for a new drill bit set. I have no issues with bent bits but stay busy ordering replacement bits for the ones that break. I know drill bits break and I have broken my share over the years, but have never experienced anything like this. I use my bits mostly with wood and hardwood and have been averaging two or three uses per bit on the smaller ones before they snap.
