Has anyone had experience with Craftsman brand drill bits? I bought a30-piece Black & Decker drill bit set for $10 from Wal-Mart a few years back. At the time, I didn't have ANY drill bits, so I was glad just to have SOME drill bits. I am not happy with how well they have worked (some broke), so since then, I just went to Sears and bought a single bit in the size I needed. I bought one "cobalt" style drill bit, and it went through a hard steel pipe pretty quick! Well, it is time to quit playing 1sies-2sies and to just buy a whole set. They have 3 different 29 piece (1/16" - 1/2", by 1/64" sizes). Black Oxide is $60. Titanium Nitride is $90 and Cobalt is $100. I am thinking about buying the $100 set of 29 cobalt drill bits. I would just use those for hard metal. Besides that set, I was thinking about getting a $60 set of black oxide drill bits. I was planning to use those for for wood, plastic or soft metal. Does anyone care to share their experience with Craftsman drill bits, or experience as to which set of bits I should buy/not buy? If it helps, my drill is a cordless 14.4 volt Craftsman, and I use it maybe once a week.
