Drilling new hole in SS sink

16 years ago

I bought a 3-hole sink and now want a 4-hole. What is the tool of choice for cutting a hole in 18 gauge SS? For a home shop, is some sort of hole saw appropriate? Thanks for any suggestions.

I would use one of those cone shaped step drills for the cleanest hole. SS is nasty stuff. A hole saw will probably work, but is likely to leave a ragged hole.

Go to a rental shop and ask for a chassis punch.
There are manual and hydraulic units.
Most rental places have the hydraulic units and a decent set of punches.
