Irwin Tools 4935607 Titanium Nitride Coated High-Speed Steel Drill Bit Set, Pro Case, 15-Piece

Cut hole in metal bracket on fence. No problem

Good quality 👍

I wasnt sure if these would be the same quality as store bought ones, or some knock offs, but they seem great! I have used them on steel, and they seem the same good quality as the irwin ones Ive bought at the store. So a good deal on a assortment. I will purchase another one. Maybe a couple more :)

I purchased these for work. I work on heavy duty diesel trucks, used these for the one box. Perfect for drilling through the thick metal to install an awning.

Good sharp drills may quick work of drilling in wood or steel. Thin one snapped easier than I expected but a good cutting edge would need a brittle steel at this cost level. I will use greater care or a drill stand for the thinner drills.

I got a set of these years back. I have never had to sharpen them (and I built theater sets and props, and did a lot of drilling). They are the best drill bits I have ever owned (and, word to the wise: don't buy DeWalt bits).The common (but small) 1/16, 3/32, and 1/8 sizes are often lost or damaged - this set has an extra of these sizes.

I'm using them basically every day (almost exclusively with wood, though), and they are great. They are - and stay - sharp. Definitely an upgrade compared to the hardware store ACE drill bit set I used before.

I have owned this set for 2 years and the bits still work like new
