I'd vote no. My experience is with wood or thin metal.
If the shipping company will send - it will go - Great product - This is a deal compared to buying the bits individually
I don't believe they are. Drill bits are usually considered a disposable/wearable item. As far as I know their hand tools are lifetime warranty and that's it.
These will work with stainless but as you know if you are drilling stainless steel heat kills. I wouldn't do to many holes with any step bit in stainless , they wont last long. The best to drill stainless is a Cobalt heat treated bit. They work the best.
No special warranty. These do hold up well - I have used another reputable brand and they last a long time. I tried this and found as good of quality but at a slightly better price and a whole kit to boot
Hi Homebrew, I drilled through 1" hollow steel tubing which was roughly 1/8 thick steel and solid aluminum... with a little oil (probably cooking oil or PAM to avoid contamination) since you are drilling a keg...I would think it should be fine. Just drill a little slower ...so you don't scorch or dull the bits. However, if you are drilling hundreds of holes a year you may want to invest in a harder strength material as they may dull drilling through that much steel and you would have to keep replacing softer material ones. Best of luck!
