Drilling through metal studs to feed cable

[veedee]

I am trying to run some cable in the ceiling to create a new lighting point.

However, I have a walls and ceiling held together by metal studs

Can the sparkies explain the easiest/ quickest way to drill through the metal to feed the cable? What bits/tools do need?

Also do I need to take any additional precautions to protect the cable as I anticipate that burrs will remain on the metal which could potentially affect the cable

Interesting. Has anyone any idea why it is said to be "specifically for cordless power tools?

I suspect that they are saying that the design has been optimised for cordless drills to allow more holes to be cut per battery charge. I don't think they are saying that you have to use a cordless drill.

Maybe !

That would, indeed, make no sense (hence my question) but the word "specifically" does seem to imply it !

The recommended rpm is 175 to 800 rpm

Perhaps they want to discourage people from using corded drills with much higher RPMs. That doesn't make much sense though. My cordless Metabo has a max RPM of 3,000 rpm, that exceeds many corded drills.

Why not email them, ask them and post back here?

Quite so.

I don't think I'm sufficiently concerned/interested to be bothered, but I'll let you know if I do! I really just asked in case I was missing some explanation which would make at least a bit of sense!

Fair call, I am not gonna lose any sleep in the meantime.
