Drilling 1/8" Steel


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


Thanks, Dave

Yeah, a good hole saw will do it. But pack a lunch if you're not using a drill press.

Re: Drilling 1/8" Steel


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.

I learned that a year ago drilling 3/4" holes in a 3/8" steel flitch plate

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

Good Lenox hole saw and something to cool and lubricate. Heat is going to be your enemy drilling it.

Re: Drilling 1/8" Steel


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?

http://www.ohiopowertool.com/p-459-h...ize-pilot.aspx
http://www.ohiopowertool.com/p-889-h...lect-size.aspx

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.

Re: Drilling 1/8" Steel


I think the Hougen cutter in HSS will be fine, just keep the RPMs down, and use a cutting fluid.

$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.
