The Bosch ones were OK, but I could make unbranded screwfix last reasonably well by using copious amounts of lubricant whilst cutting...

Starrett are very good - you can certainly notice the difference when used back to back with cheaper ebay stuff. Although I've found as long as
you get the speed settings correct and are patient (and use coolant) even the cheap red ones on ebay (cant recall the seller and dont think
they're branded) work ok. Most of my work is aluminium though.

Used medium speed with lots of wd40 - even stopped half way through to let it cool down...
Bit sick ! only have another 2 mitres to cut - Ive heard of the starrett ones will buy one of them instead.
I thought draper were ok ish .

2nd for the Starrett cutters, they're dearer, but they last longer and more importantly cut better.

Wd40 is no good it just vaporizes. Use a proper cutting fluid it will double/triple the life of the tool.

I find just WD40 burns off to quickly to be a good cutting lube as it vanishes and doesn't carry away any heat, I use engine oil on everything
including the hacksaw, will make a huge difference

another vote for the starrett ones, more money but cut better and last longer, that said if you "go for it" with any hole cutter they will
burn out, slow and steady and lots of lube.......ooohhh eeerrrrr missus!

I have a set of cheapy cutters and Starrett for the ones I use the most. As said, use proper cutting fluid, not WD40. Engine oils contain carbon so if
the cutting process causes localised heat spots at the tips of the teeth, you end up adding hardness to the work piece. If you're using enough
oil to keep the tips cool, this isn't such a problem but it's easy the 'blue' the work piece' which causes grief!

It's not "no use" since WD40 is vastly better than nothing at all, but there are much better cutting fluids.

I've used ordinary hole saws to cut 70 mm holes in 5 mm stainless with a hand drill. Trick is to turn the saw slowly, and use the proper red
cutting paste.

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.

You need slow rpm and a water based cutting coolant/lubricant -- nb coolant
Bosch ones are good as are the Orange ones sold by B&Q

I've used bosch ones but again a proper cutting oil makes a bit difference. Wd40 is better than nothing but then most things are
