Works great for stainless steel
Never any problems with these bits and I use them on stainless steel all the time. A few people have problems with them breaking using a hand drill. If you are using these with the 645-011, the trick is to punch your pilot hole first without outer hole saw attachment. Most breaks happen when the outer hole saw first grabs the metal.

It did the job
I drilled a 9/16" hole through stainless and the pilot worked well to start the hole.

super hard steel with a flaw
+These pilot bits are super hard. They will really cut steel. -These pilot bits are super hard. They will break with any accidental bending from a hand drill. I went through 3 of them in 5 holes. I drilled about 4 holes with the first one. The 2nd lasted 10 seconds. The 3rd lasted a little while longer (maybe one hole) because I was being super careful not to bend. I was drilling into steel (a vehicle frame), not stainless. They are probably well suited to a drill press. My recommendation is to drill the pilot hole with another 1/4 drill and use this for piloting purposes only. The hole cutter that this fits into is great. No issues.

Bits snap frequently
So the quick change kit is really nice, but the bit seems designed to snap so you will keep buying more. I've snapped 3 or 4 in the last 6 months. There is a step at the tip from 1/4" to about 3/16", probably to help with starting the initial hole. However, as soon as you make it through the first bit, the 1/4" part will grab and snap the bit if you're not perfectly straight with perfect trigger control. A regular 1/4" end would probably make the bit last way longer. I'll be looking for 3rd party bits from now on.

Drills perfectly without need for center punch.
This pilot drill works great. No need to punch a center mark. Just place the center of the pilot drill where you want to drill, hold it steady and start drilling. I've done several holes in 18 gauge steel and each started exactly where I wanted with no wobble or tracking, exactly as advertised.
