5 Stars Good wood bit?
Does anyone know if these make for good wood bits? I know they’re excellent for metal work from the reviews, but i’ve heard mixed reviews that the steep angle on the tip makes the bits grab into wood too quickly, causing chunks of wood to splinter. Anyone know otherwise?
5 Stars very high quality
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 the material rather rapidly.
5 Stars Bosch Cobalt Drill Bit Set
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.
5 Stars Cut through steel fast
These bits are fantastic. I used one 3/8 inch bit to cut 24 holes in 3/16 steel almost like it was wood — very fast. No sign of dulling. Excellent bits, but one small one was missing.
5 Stars Great Drill
It is a good-solid drill. A little on the big side, but still a good product.

5 Stars Great Product
Very high quality. Much better than a name brand diamond burr I purchased at the hardware store (one of which cost 3x what this entire set cost).
4 Stars Diamond Bur Set
The burs are fairly sturdy. If grinding and shaping remember to keep moist with water or lubricant. Otherwise you rip off the diamond surface (did this, not thinking). Some of the finer bits break easily, but the rest do the job.
5 Stars Efficient for crafts
I bought this item to use for my jewelry craft items. With these bits, I can drill small holes through seashells, beads & glass without chipping. The bits work perfect in my Dremel tool. The diamond part does wear down after drilling a lot, but for the price I think it is a great deal & it gets the job done.
5 Stars 30 piece burr set
This is a very good product. 30 is a lot and it covers all you could need. I work with silver and have a drill stand in the club and often need different sizes so this was ideal.
Packed very well to be able to see just what one you need at the time.
5 Stars Super Nice
I have just started learning to engrave, and had been using the accessories that came with my rotary tool, but then I got this set and they are pretty much all I use now. So many new options have been created since getting this set. I highly, highly recommend this set for anyone in the engraving craft.
