If you plan to use these, or ANY drill bit in metal (other than aluminum or very thin metal), invest in a bottle of cutting/threading oil. The main killer of bits is heat. Thread cutting oil not only cools the bit but also reduces friction and heat. Even the best bits you can buy will go dull if they get too hot.

You get it in the plumbing department as it is usually used with pipe threaders. You can get a 16oz bottle of Oatey brand for $7 and it will last forever.

Dip the tip of the bit before starting and frequently while drilling. A bottle cap works well, I keep a nice deep bottle cap full of oil around for this purpose, but any small container will work, and one with a cap will prevent accidental spills when not in use. Or you can just drop the oil directly on the bit (a little more time consuming). Use the drill on low speed. For drilling larger holes, place a drop of oil in the hole periodically while drilling (in addition to dipping the bit).

It has other uses too, you can even use it with sawzall blades when cutting metal to extend their life (though that gets a bit messier). Basically use it on anything with sharp teeth when cutting metal.

Shows $12.98 on the Lowe's app for me. Maybe this is just an app deal. Just ordered.

Looks like it's a "new lower price" deal. If you scroll down in the app there are actually several drill bit sets marked down, if you are in the market. I wish they just sold a set of the smaller drill bits. I have several sets missing the smaller ones!

Gold oxide coating is great in the kitchen and grill ,for that piece of "steak" the in-laws bring over and you can't get a temp probe into .
