Amazon.com Product Description

The Irwin 29-Piece Cobalt M-35 Metal Index Drill Bit Set includes drill bit sizes measuring from 1/16 to 1/2-inch in 1/64 inch increments. The 29 bits are made using heavy duty web construction for strength and durability, and the cobalt steel extends the life of cutting edges. The 135-degree split point tips start drilling on contact and cut with less force. A reduced shank above the 3/8-inch point lets you use larger drill bit in a 3/8-inch chuck, and you can select the right bit using a convenient tap and drill selection chart. The set's rubber overmolded case protects against damage from accidental dropping, and you can remove cartridges to easily carry bits from the case to your worksite.

5.0 out of 5 stars Almost A Regret?, May 14, 2009

I took on the project of building my new shop. I've made numerous purchases and saw the Irwin Cobalt drill bits. It was as close to an impulse purchase as I've made, and I quickly regretted my decision as the set was pretty expensive. I figured that when they came in if I didn't like them I could return them.

Well they came in and I was very impressed with the quality and sharpness of the bits. This is by far the BEST set of bits I have ever owned.

If you compare the costs of 'throw-away' drill bits, and then figure the frustration of having busted small bits...then look no further than this Irwin set.

It is worth it.

This review is from: Irwin Industrial Tools 3018002 29-Piece Cobalt M-35 Metal Index Drill Bit Set with Case (Tools & Home Improvement)

Got these bits a couple of weeks ago to replace a 20+ year old Craftsman set. The first thing I noticed was the heft of the assortment; same number of bits as the Craftsman, but considerably heavier. Have mainly used a couple of the larger ones on a cast iron grill; they chewed through like it was pine. Have used some of the smaller bits to drill out rusted bolts. You only need to watch the metal filings pile up to know they're doing their job. Haven't used any on wood; seems like overkill and my older ones do fine for those. I only wish the storage box had a more positive lock mechanism. But I do like its bright size markings (sure beats stamped metal, which I can never read in weak light). All in all, I'm very pleased, and the price was GREAT!.

I know Cobalt (both M-35 and M-42) are way more expensive than regular HSS drills, but if you've got exotic metals or steel to drill it's like night and day. I wouldn't go back to HSS except for wood and maybe aluminum after this!
