Outer Limits 4x4 Board

ok well ive normally brought the standard 2.5mm cutoff discs have recently tried the 1mm thin cutoff discs and was really happy with them but they dont last long

im looking at getting a Tungsten Carbide Metal Cutting Blade at around $20 each and im hoping that there a good thing and will last a while ??

any one care to comment on them
for infomation sake these are what im talking about

FWIW, I bought one of those real thin cut-off discs when I needed to cut back lots of sheeting for my garden shed. The first one disappeared during the first cut, but the next one lasted a lot longer - maybe something to do with technique?

Cheers,

The thinner they are the better they cut, its a toss up between using a thicker disk and taking ages or the thin one and go through a few quickly.

Can't beat a plasma cutter though

1mm cut offs are cool, we go through a box of them every couple of days. They cut out less material so cut quicker, but yes get used up quickly.

Ah but Casey remember what out forfathers used

The tungsten carbide blades are noisy as hell and bloody dangerous, but they work well (on 3-6mm aluminium - never tried them on steel). I would keep the guard on (or refit it) if you don't want to lose and fingers (if you aren't holding the angle grinder firmly enough when it bites).

I usually use the thin discs and buy them in bulk.

i have used the steel one and cut the rear end off a troopie including chasis. works great never bit in however i have had that happen with the alley one
Well worth the money

A couple of recomondations

ensure you have the guard on

and wear heavy gloves the swarf is bigger and hot

keep the grinder going flat out at all time while in contact with the metal

I cannot recomend a better cutting disk than the 1mm cheeze cutter, do not force it along the metal , let it cut the sheet( a mate who is a heavy handed tree loper, only was cutting half a sheet of tin to a disc, I managed to cut two and a half sheets, so it is technique...

I have pretty good success with the 'pferd' brand mega thin cutoff wheels, in 4", 5" and 9", think even the 9" ones are only 2mm thick and I find they last as long or longer than the thicker cutoff disks. cut much faster and put a lot less heat into the work.

does anyone have experience with the carbide wheels? I am scared that they will blunt really quickly and just put a lot of heat into the work.

cheers

If you can use a grinder proply and put the disk on the right way they will last a lot longer and also cut quicker and the thin ones are good for stainless.
