Driling to Stainless

Ok need to put my nice new anchor/nav light onto the 4mm ss plate at the top of my A-Frame.

Is Stainless any differetn to drill through than normal mild steel.
Or am I in for some trouble getting through it?

It's a bit tougher. Good quality sharp drill bits take it nice and slowly and use some cutting fluid and you should be ok

SS is a lot harder than mild steel. They make TCT bits (Tungsten Carbide Tips) for this application.

Stainless work hardens at the slightest provocation, so as said above - go slow & steady.

Start with a smaller drill and work up is the safest way forward, plenty of cutting oil to keep things cool WD40 if nothing else is available.

to drill or not to drill

Use two drills and a lot of cooling fluid.
steady not to slow but please DO NOT stop during the drilling. if you do that it l harden and super tough.

kobalt drill bit is ok.

grtz
