Do these work with the small 1/4 drive impacts?
Why do they advertise this as 7/8-Inch-1-1/8-Inch. Looks like it also does up to 7/8?
has anyone used these with stainless steel ? im looking at regular use with ss electrical panels and sheeting up to 1/4" thick.
Does these bits come in a carry case or bag

Dewalt Unibit

I used it out on the field and was impressed with how quick it drills and how resistent it is it's worth the 20$

Best bit EVER?!

Literally… The best bit I’ve ever used.Now. I’ve yet to test it on hard metals like stainless steel, but it ATE through soft metal and very cleanly at that!

The best bit in the world!

THIS BIT IS FREAKING AWESOME! I SHOULD'VE BOUGHT THE 3 PACK!

Holy cow batman, this thing works great!

The media could not be loaded. I don't know what it's made of, but it is hard and sharp. Goes through structural steel so much better and faster than other drill bits that are supposed to be good. I haven't tried it on stainless steel yet, but the holes it drills into structural steel are comparable to how good individual M35 bits perform on structural steel, and since those same M35 bits will go through stainless, then I'm confident this Dewalt step bit will go through stainless steel just as well. I will have an opportunity to test it on stainless steel in about a week from now and can give an update afterwards.Update: I picked up 2 other step bits, one Oxmul M35 (5% cobalt) and one Stroton (6% cobalt). The Dewalt similarly outperformed those as well. I drilled stainless steel with the Dewalt and got a surprise---it quickly accelerated in expanding/drilling out the hole once a pilot hole was created. All drilling was done with moderate even pressure at relatively slow speed.

Drilled steel like butter

Drill bit was recommended by vendor I purchased the accessory I was mounting. Used it to drill 6 holes through a heavy steel loader bucket on a tractor. The smallest step took a bit to punch through at the recommended slow speed setting, but once that tip made it through, the next steps on the bit went quick and easy with nice clean holes at the finish. I didn’t need a file to clean up any edges as I often do when drilling steel. Great drill bit.

The best step bits I have used

These step bits stand up to constant torture and remain sharp. I have cut through 1/2" plate steel with them (though I am sure that is not advisable) and was able to make clean holes. These bits are more expensive than some, but for the quality I think they are worth it.
