I agree that this is a great deal for around the house type stuff. For those who may not know:

1. The masonry bits only really work if you have patience and a drill with a hammer feature. An impact drill is not the same. Depending on the material and size hole it could take a while, especially in concrete.

2. The metal drill bits are titanium and won't hold up to abuse. Get some cutting oil and if it's a thick piece of metal try letting it cool down a bit in between holes and it will preserve the longevity. Also more force = faster damage to the cutting edges.

3. Metal and concrete will destroy wood bits. Metal will dull masonry bits. Drilling too fast in wood with a masonry or metal bit can overheat the cutting surface and prematurely dull the bit.

I bought this set 5-7 years ago, and it is great for weekend DIY warriors! Saved me lots on money on different drills bits! Would highly recommend as a gift or having it

Weirdly Costco.com is having some serious issues with loading today. And when it does, I couldn't add this to my cart.
