Has anyone out there used this knockout to punch a hole in a 18 gauge stainless steel kitchen sink?

Thank you...

I think you would be hard pressed to find an electrician with a need to make a hole in a sink. Need to check with a plumber.

Having a little fun at your expense:D .

The slugbuster works fine on stainless steel, we use stainless steel junction boxes, and other various electrical equipment in wet or corrosive locations and we always need to make knockouts for conduit entries.

Just take it slow, let the tool do the work.

When we make a 4 hole sink out of a 3 hole stainless steel sink we use a Greenlee Hole Punch,(see image).

. Drilling a Stainless Steel Sink For a Extra Hole:
(1) Position the large chrome washer on your sink where you want to install it. Make certain there is enough room to fit.
(2) Feel underneath the sink to make certain there is no obstruction that would prevent proper faucet installation.
(3) Center-punch sink in the middle of large chrome washer.
(4) Using a standard steel drill bit, drill a 1/2" hole.
(5) A "Greenlee" hole punch, (see image) must be used to even out a drilled hole in a stainless steel sink and bring it up to the correct size.
Good luck, Tom

Thanks Speedball1,

It worked just fine. I made a hole in my undermount sink for a air switch.

Thank you guys for your answers.

Tkrussell, Are those stainless steel junction boxes 18 gauge? I've never seen one, but again I have not been doing electrical as long as you and neither I do commercial work.

Most of the staineless steel enclosures we work with are thicker than 18 gauge.
