How do you drill through 3/16 steel?
 

Without a drill press. And how long would it take you? And how many pieces could you get through before the drill bit was dull?

Dimple the metal, use one size smaller and they will be junk when finished.

How long would it take you?

The best way to do it is start out small and work your way up. Good metal bits will go a long ways and take your time or you will destroy the bits. WD-40 helps too.

Thats what I would have said this morning. But how long would it take you guys? 20mins?

What if I told you guys I could do it in about 60 second, no predrilled holes, no wd40, and the drill bit will last indefinitely long. No evidence of dulling after doing 10 pieces.

I have some very expensive drill bits that will do it too, however I don't like to use them. The tool makes all the difference.

There are a lot of parameters there dude? What kind of steel? What kind of bit? How big of a hole? If we're talking mild steel and your average metal bit, WITH CUTTING OIL, working from a dimple, up in size to something not too huge 20 minutes per hole wouldn't surprise me at all and no you wouldn't get a whole lot of holes before the bits started to dull. In any case, use cutting oil!

I've never seen a drill bit that can do that, and that fast. Not even the carbide ones.

I'll see if I can post a video later.

Id love to see a drill bi do it that fast. The size of the hole makes a huge difference too. Good stepper bits work great, never tried them on anything too strong though.
