Driling to Stainless

[jezza2011]

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?

[Roger Marr]

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

[EnglishLes]

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

[Downhilldai]

Sharp bit, slow speed & use cutting paste.

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

[chewy]

Slow steady and lots of lube

[Poly]

its an 'ole drilling thread this should go on for a bit!

[Hightower]

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.

[diverbert]

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.
