great for hobbyist use

Good set for working with soft metals with one caveat: upon penetration these bits pull the worked piece towards the drill quite agressively. Otherwise they are very effective, and the extra bits offer that assurance that you won't have to pause a project should you accidentally break one of those sizes.^M

The case is a bit bulky compared to other drill sets, but that's actually a good thing -- it's deep enough and there's enough extra space above the large bits to hold a 1/4" cordless screwdriver/drill chuck adaptor. (YMMV, mine is a Skil #92170)

DEWALT DW1263 13-Piece Cobalt Split-Point Drill Bit Set: Nice set product and packaging wise!

Great - cuts like I'm drilling soft wood all the time

I bought htese because my old drill kit was missing a few bits and they were getting old. I had no idea how dull they were until I bought these. The effort required to drill holes was minimal. No more pushing hard and smoking holes from the heat of a dull bit.^M

Sure, I could have sharpened my old bits, but for the cost of a Drill Doctor, I can buy enough of these sets to last a lifetime.
