any one got suggestions on some decent holesaw brands?
my lame ones decided to annihilate themselves on 10mm polycarb (such a savage material it is too lol) the little grub screw that holds the boss to the drill bit has just stripped out.

The blue Sutton Tools holesaws available in Bunnings are as good as any. I have also used Sandvik and others - they all seemed to have similar performance.
An important point with these holesaws is that they have a seperate shank and there are at least two ans sometimes three different shanks for different diameter saws. The shanks from one brand almost never fit another brand, so I would pick the local Suttons saws as they are the easiest ones to get; you don't want a big collection of spindles from all the brands _________________ Australian 2015 Featherweight champion

The heavy duty holesaws have a hex shank to fit in te drill chuck. At the end of that is a short threaded section that screws into the back of the actual hole saw. The shank is hollow to accept a pilot drill, which is held in by a grub screw. Once the saw is screwed onto the chank, its a very strong & rigid setup, the only problem is getting them apart when you want to put a different size saw on the chank. _________________ Australian 2015 Featherweight champion

U mean the type you whack with a hammer? It sounds OK but not an outright steal. I think I paid around $25 for one with 4 bits and a steel box. _________________ Australian 2015 Featherweight champion

I think he meant made out of steel lol .I bought one from K mart about 15 years ago for about $9 at the time and ive given it a caning over the years and have had to get replacement bits for a couple of the drivers it came with 4 flats 4 philips bits and 6 allen key type bits .As i repair mowers and smal engines i use it a lot to undo case screws and bolts most of the driveres you can take the end off and put a 1/2 inch socket on them as well.

I would suggest wearing only inflamable materials as there is nothing worse than after grinding a piece of metal to look down and see your groin on fire! _________________ Get Some!!!

inflammable is the same as flammable; "easily set on fire". You want something made of heavy cotton or wool, which is naturally fire retardent. Synthetics are the worst thing to wear, they can melt or catch on fire. Grinders just make everything dirty and the only real fix I know is to have a set of old workshop clothes or an apron. _________________ Australian 2015 Featherweight champion

I'm getting a set of new power tools for my workshop for my christmas and birthday pressies...
I'm after a good but fairly cheap:
>Drill press (bench mount, the supercheap auto ones seem ok)
>Abrasive cut off saw ( they have them too... but no idea on quality)
>Bandsaw ( maybe... still thinking about it)
The reason for the cut off saw is my parents are worried about me using the "all evil" anglegrinders, and i need to cut steel fast! _________________ ( •_•)
