This step drill bit worked perfectly.
BP
It works but you need to make sure and use a low speed drill and a high quality cutting oil.
Pat
This cut through a large stainless steel kettle like butter.

I really wish this came with instructions. Without them I ruined my bit in 5 minutes. After ruining it I looked up how I should have used it. Ideally this should be used in a drill press with a constant flow of coolant. However, if you are cutting a keg (like I am) with a hand drill then you must only cut 15-20 seconds at a time, wait 60 seconds, wipe the old oil off and add more oil, repeat. Never let the bit get hotter then you can touch. Second never run the drill quickly, slow as you can. Fast apparently can heat the SS fast enough to harden it.
The final note I found is never use a steel file or brush on stainless steel. If you do it will embed little microscopic bits of stainable steel in the stainless and will cause rust. De-burr with either a stainless steel file or sand paper.
I know all this is stupid obvious to anyone who works with metal, but judging by the reviews most of the people buying this are brewers not metal smiths. Oh well $14 lesson learned, hopefully the next guy can learn it for free.

This drill bit did exactly what I hope it would do. I drilled a 7/8 hole through my stainless pot with ease. My ball valve fit perfectly.

Good value for the money.

Have used a few times on electrical cabinets, galvanized boxes and thin stainless steel. I've kept it well lubed during use w/ high viscosity cutting fluid and haven't noticed any dulling or overheating. I like the large size because I can drill one or two holes quickly and the mass serves as a heat sink keeping the cutting edge cool, after that it gets put away till next time.

Doesn't have the feel or weight of higher quality bits so I don't know how it would handle extended use, but that's not what I need anyways. This gets the job done and is good enough since it gets used very sparingly and I saved a bunch of money to boot.

I needed to drill a 1-3/8" hole in a stainless steel kitchen sink (not sure of the thickness, but it was a heavier gauge than some of the less expensive sinks I've seen) for an instant hot water device. I had another step bit that wouldn't touch it. This one did the job, albeit with some time and effort. I started with a 1/8" bit and worked up to 3/8" or 1/2" (I forget which) before using the step bit. Then, I drilled one step at a time using liberal amounts of cutting oil, it cut slower as the hole got bigger which makes sense as it was working harder to remove more material. The key to the job was letting the sink and bit cool down between steps (cool water helped speed up the process and also kept the sink from warping). I had my wife drizzle oil on the bit/sink while I drilled - messy but effective. Bit seems to have survived just fine, still feels nice and sharp. As an aside, we love the instahot, too - it was worth the effort!

I drilled a 7/8" hole in a bayou classic stainless pot in less than 10 minutes. Unlike many other reviewers, I had no problems at all the whole way through. I even used it to remove the various metal burrs and smooth out the hole when I was done. Worked great, especially for the price.

Keep in mind that I'm a total noob when it comes to any of this. I've never drilled a hole in anything in my life, much less in stainless steel. My method was as such:
* Used WD-40 liberally on the bit and on the pot, including the inside of the hole once I opened it up.
* Used a Makita cordless 18V drill I bought on sale not long ago, set to the "1" setting - low speed, high torque.
* Created a starter dent with a center punch (B0006J4K88
* Drilled a 1/8" pilot hole (B00004RGVZ
* Set the pot down on a cloth outside. Started drilling VERY SLOWLY while applying a fair bit of pressure to the drill.
The idea was to make sure the drill was constantly cutting into the metal instead of spinning and smoking.
If the drill is spinning but isn't actually slicing through the metal, all you'll do is work-harden the steel and wear out the bit.
* If the drill starts smoking, stop and let it cool. Re-lube before starting again.
* At each step, stop and let it cool, then re-lube before starting again.
* At the end, briefly run the bit at high speed on the inside and outside of the kettle to smooth the edges.
* Scrubbed everything with soap, because WD-40 stinks.

This cut through a large stainless steel kettle like butter. Can't attest to how long it will last but I see no reason why it would not last for a couple dozen holes. Just make sure to use low RPM and a quality cutting fluid like Tap-Magic extra thick. Excellent product for the price and a good tool to have in the homeowner/hobbyist arsenal.

I bought 3 of these to drill out an extra hole for conduit in a circuit breaker box and to drill an extra hole in a stainless steel kitchen sink. I was able to drill the soft steel in the circuit breaker box just fine, but all 3 bits dulled quickly and started burning when trying to drill the stainless steel kitchen sink.
