I discovered these in my short period as a low voltage electrician and just kept them in mind when I came into the heavy equipment trade and they work equally as good for battery shut offs, bulkhead passthroughs, or even just adding larger holes on a roll cart for ratchets and prybars without messing with a unibit. I have 2 sets of their larger sets from 1/2” - 2” with the ratchet that I got for a steal
I needed one of these when the holes in my LED under cabinet lights didn't line up with the holes in the fluorescent lights I was replacing. The step bit I tried first left too jagged of an edge, but was good enough to drill the hole required for the knockout punch. I wasn't going to pay over $200 for something I only needed to use a few times, so I got the Harbor Freight one for $20, but $30 for a name brand is a steal.
I had picked up a set of these with the ball bearing feature from a pawnshop for $15 one day and they have been sitting on my shelf for years waiting for something to do with them because I put them in the electrical tool category. I do a lot of automotive fabrication stuff and didn’t realize they’re rated all the way down to 10 gauge mild steel and the smaller one in the set only needs a 3/8 inch starter hole. These are going out to my auto shop now for fabrication stuff. It is very difficult to enlarge a hole through sheet metal that already has some odd size hole in it. For instance, if you need to run a wire loom through the firewall, but there’s only like a half inch size hole there, this would be awesome. I have been using step drill bits but they’re kind of crazy sometimes.
Hello again, Catus Maximus and Tiny Thank you for another Great Video 👍 I remember the name Green Lee. But I am remembering a bearing tool? For install/removal. Again thank you 😊
Howdy, Brother! Nice find! I/we appreciate your daily, dedicated tool reviews and tool teardowns. Thanks again and Drive-On, Cowboy!! 🤠
Found a slightly larger set at a swap meet for $40. They worked great when we were building body panels for the race car.

Thanks a bunch!😊
Things have moved on .
I run a business selling a hydraulic battery powered version of this tool.
I’ve used the Milwaukee version. But these are still on job sites. At least the hand pumped hydraulic ones.
