Which holesaw?
I need to cut some biggish holes in 3 & 6mm steel plate.
Say 2" up to 5"... in the past I would use the drill and file method but theres too many to do atm, I'm looking for something
better, but still cheap!
Any ideas??

I have a bi metal hole cutting set again if you want a borrow, how many do you need to do?
I'll have a measure tonight as I know I knackered one but can't remeber which size.
Cheers

A set of decent HSS holesaws should be fine for this. Though I've not tried anything as big as 5", I've had good success going
through 5mm mild steel up to 3". Only advice is to avoid the super cheap £10-a-set holesaws, and to use plenty of cutting lube.

Axminster sell some really good HSS hole saws...
I had no problems using a 4" cutter on 3mm Mild Steel plate... just make sure its well cooled!
You do need a BIG drill to be able to turn it though!

I find the orange ones B&Q sell are fine for 60mm holes in steel, --- slow speed lots of coolant.

I would just add that the job must be well clamped down, rotating speed of holesaw set as per instructions and use a pillar or pedestal drill not a
hand drill!!

"not a hand drill!!"
I would definitely second that! I'm sure some of you remember why!!! 
If you have to use a hand drill then very slow speed & a clutched drill - don't ever use it above chest height!
It's healed reallly well now BTW as any of you who saw me at Stoneleigh will have seen!
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names

Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

the bosch cobalt range are superb, I use them a lot, but not 100% certain if they go as big as you require
quick release with hex drive, the trick with holesaws is slow and well lubricated, take your time
I used a 1" holesaw and put 4 holes through 1" plate with it, still going strong 
I would certainly reccomend them, I get them from screwfix
heavy is good, heavy is reliable, and if it breaks, hit them with it

Gavin, if I looked like you I'd probably have kept going with the holesaw & gone for a complete face transplant!!!
