I wasn't sure where to put this. Ok I am adding two small led work lights in the bumper on my utility body. The bumper is 1/8" powder coated steel.

Long story short, I added some to the body, but the bumper has clipped corners. So these lights will shine out to the sides a lil for backing trailers at night. I don't want to put them under the bumper because its pretty low.

I have to drill two 2 1/8" holes. Do you guys think a high quality hole saw and cutting oil will handle this? I would even buy one hole saw for each hole.

I would hate to start drilling and have the hole saws not work:laughing:


Thanks, Dave

I watched my plumber drill a 4 1/2" hole in a 3/16" steel panel on a grease trap the other day. Took him 2 $40 Lenox hole saws, but he went slow and kept spraying water on it, and he got it done.

If it is not hard steel, one bit should be fine! Go low pressure and slow. Get 2, save the trip to HD for the other! lol IF ya need a gorilla to help out, My son is available!! LOL ya know who he is!!!! Chad. ask dad!

Thanks for the input guys, that's good news!



Yeah, a good hole saw will do it. But pack a lunch if you're not using a drill press. :laughing:
I learned that a year ago drilling 3/4" holes in a 3/8" steel flitch plate:laughing:

Needless to say after about one hole I went and rented one of those electromagnetic drill presses:laughing:

I find that a hole cutter usually works much better than a hole saw for 1/8 steel, especially if you're using it with a portable drill. They cut cleaner and faster with less heat and run out than hole saws so your lights will fit in the holes better. Hougan is the brand I use, so they are what I would recommend.

Wouldn't he better off with the carbide version for 1/8" steel?

The 2 1/8" HS version is $27 at above site, & the carbide is $54.

I've cut more than a few with a std carbide hole saw. You just need to use max 500 rpm, spray with WD40 now & then, & do a sloooow wobble so as to get enough pressure on the teeth to cut, instead of just dragging off fines. It's kinda similar to rocking a hand saw when you cut wood. The tooth pressure has to be right to dig in.

$28 for 2 lenox hole saws or $70 for the kit for the Hougen kit. Especially if you have the mandrel for the holesaw already. You can get the holesaw sharpened again for about $4-6 at your local sharpening place.
