This drill bit set has replaced a whole drawer full for mis-matched bits. I have used them in both the drill press and the handheld drill. I've been impressed by their ability to keep an edge and the sizes this set offers have served every need I'[ve had so far. i use them in wood, soft metals and even hard metals. Like all precision bits a little every care should be taken not to over-heat them, but with a little common sense you'll enjoy this set for years.
Bought these to keep in the wall cabinet behind my drill press. I got tired of going back across the shop to my main bench area to get my titanium set that are also Craftsman, but are about fifteen years old and still cut just fine.ive only used a couple thus far to drill some mild steel, but they seemed to work just fine. Cobalt is really only designed for metal working, so if you need an all purpose (no cement, or stone) set of bits, spend the extra $20.00 and get the titanium. They are designed to drill metal,plastic, plexiglas, even wood if you take your time. Otherwise this is as good a bit as I've found as of late.
Bought these to drill 2 holes in my 3/4 ton truck frame (mounting a winch plate) and the largest one cut right through, no problem. Can't find any faults; they cut through hard metal with ease. Love 'em.

I needed a heavy duty drill bit set for some tough home improvement projects. This kit fit the bill and is very well packaged and organized. Attractive looking and durable.
Extremely satisfied with this set. Great quality, durability. I used them to drill a hole in a head bolt... No comparison, like s knife in butter. This set contains the most popular sizes.
Drill bits are nice. The measurements are on the body, not on the shank, which is a good thing so the size doesn't get wiped out if the bit slips in the chuck. The case: Meh, it is tough to get the rear most bits out of the case since the case doesn't "clamshell" or cantilever like other cases I've owned. Also, there is no clear plastic windows in the case. Not that it really matters, but in looking at the case, you would think it was fully enclosed. I guess you don't have to worry these bits oxidizing.

One uses cobalt bits mainly to drill in metals - especially ferrous metals such as steel or iron. You can use it to drill other materials also such as wood, plastic, and non-ferrous metals such as brass and aluminum. I was pleased with the quality for the cost I paid for these bits. I have used them for general pulse use as well as drilling steel and cast iron. Cast iron is very hard and can be hard on drill bits. Be sure to use lubrication when drilling metals - especially steel and cast iron. By the way WD-40 is great for non-ferrous metals, and light machine oil is best for steel or iron. It helps protect the bit from premature wear out. I did eventually dull the 9/64 bit on cast iron - but I had failed to provide lubrication and drilled several holes in cast iron. On the whole I am pleased with these bits.
I needed to drill out a 3/8 inch broken muffler bolt. It took the use of at least 8 drill bits, starting small and progressing upward, to accomplish this! Even though I was using cutting oil liberally, the larger bits would stop cutting after a very short period and were useless. They even spun in my Dewalt drill because of the smooth shank. The cobalt coating is only microns thick and burns right off leaving you with a dull, soft-steel drill bit and a cute box for your $100 bucks! Tomorrow, Sears gets them back and they should be taken off the shelf.
