Drill and tapping Chrome parts

[Espeefan]

Does anyone have any advice for drilling and tapping holes in chrome parts? Is it better to drill and tap holes before chroming, or after? Does it really matter? I am sure if I drilled and tapped holes in parts to be chromed, as soon as I got them back, I'd have to at least tap the threads again. That's why I wonder if I should just drill the holes to size, for tapping, and then tap them when I get them back from the chrome shop.

What does everyone think?

You can also get oversize taps to account for the chrome plate thickness. Something like a H7 or so. Talk to your plater about that and they should be able to suggest the right size for you.

Thanks Jeff. I'll look into that.

You could always drill & tap, and then screw a screw in it while it is being chromed. When you get it back from chrome, remove screw. Then you'd have some chrome screws.

And a rough edge around the hole where the screw was removed...
