I need to cut an 80-100mm (unsure of exact size yet but that's not too important) hole using a hole saw............i will need to do this around 350 times in a short space of time. Short space of time = it needs to be quick at the job!

Can anyone recommend me a really good top quality hole saw? It'll be cutting through laminated chipboard if that matters.

The materials i'll be cutting are already screwed in place and the area i'll be working in to drill the holes is no bigger than the inside of a PC case, maybe 500mm width and height. (obviously not all 350 holes are in he same area, 2 per "box" as it were) so i also need a suitable drill for the job, one that i can get inside the box and is going to be safe, or in other words one that's not too long that i can't get my hand behind it properly.

I was thinking of this: http://www.screwfix.com/p/adjustable-hole-cutter-with-cowl/48984# but i've no idea how that'll cope after a couple of hundred uses.

Any suggestions please? My knowledge of manly tools is pretty slim :p
 
Thats a cracking hole saw! :eek:

Mine was £3.50 including several blades to cut wood... I know the feeling though.

Drilled about 300 holes in my fence recently...

We've currently got a set of different sizes but they've seen so much use that it takes 10minutes of in out in out shake it all about to get it to cut through a simple 1cm thick piece of MDF :( Decided it's time for something less dangerous (ours is leathal!)
 
That holesaw will kill you after the second attempt at using it. Don't even dream of buying it. You want it done quick so you spec the crappiest 'one for all' type tool. No. Get something robust. You missed the deal on how thick the laminate board is and if you need it to b a dead clean cut or if it'll be hidden from view?

Use this opportunity to buy a quality drill. like this. http://www.screwfix.com/p/dewalt-dwd024k-gb-650w-percussion-drill-240v/59025

good quality drill with a useful and strong front handle, for the holesaw Screwfix home brand (the red ones) or Bosch. You'll need an arbor too.

Aye the one linked to in op is for plasterboard at most. I doubt it would even scratch laminate.
 
Get the bosch one listed underneath. You dont need a hammer drill unless you are drilling masonry. Any old crappy corded drill should work.

You don't need a hammer drill for hole-cutting period.
You need something reliable, that has some nice smooth deliverable power, and that has two good grips so that when that 100mm holesaw catches slightly it doesn't take your whole arm-face with it!

Thank you for your helpul (yet slightly patronising considering i admited to not knowing what i was looking for) reply :) I'll no doubt get a spare or two of the hole saws as they're so cheap too!
 
Love Bosch However..

The only thing you might find with the Bosch "Powerchange" range is that the hole saw is not perfectly rigid in the arbour and as such can make a mess untill it finds its way into the material. I used a 25mm one for my fill port in an old case and it jumped around on the ally trying to find its way in.

So yea buy a screwed-type IMO instead of that "powerchange" crap.
Erbauer are good.

I'll slightly agree with this, the quick change can be less than 100% at times. You can however unscrew the bosch quickchange neck and use it on a standard arbor, giving you the best of both worlds :)
 
What thickness material are you going through ? Although whatever holesaw you get, its going to be blunt before youve finished.
 
350 holes? You're going to need a good drill, as using a large holesaw really puts quite a lot of stress on the drill I've found...

As for holesaws, I've found the screwfix ones to do the job, but you'll probably need more than 1 cutting that amount of holes...
