Novice has small angle grinder (takes discs 115 mm with central hole

tiles and metal.

Having knocked down a very old cedar garden shed, I want to cut up
all the wood. I'm wondering if i buy one of the diamond discs
available for it, whether that would be reasonably ok for cutting
wood with? I cannot find any discs that are said to be specifially
for wood for this type of angle grinder.

Some of the shed cladding wood is very thin (with nails all over the
place) so i think the usual circular saw for wood would be a bit too
hefty and vigourous on this thin wood of the shed. Grateful for any
suggestions on the best type of circular disc to go for. Thanks.



I saw some discs in Alsford Timber the other day that were available
in 9" and 12" (might have been a 4-odd inch too) that were advertised
for wood, especially tree roots. They had some almighty lumps
(1/8-1/4") of abrasive (maybe carbide) suck on the side. Looked
bloody viscous - sadly I can't remember the name.

A google for angle grinder and tree roots might turn up something...
Or ring Alsfords in Hastings (assuming you're in the UK) and ask them
what those ******* evil discs on the front counter in the display
stand are called...


diamond discs would gum up from resins and overheat quickly.
They are made for ceramics and metals,not wood.


It wasn't a diamond disc - very clearly nothing like one to the eye -
in fact I've never seen anything like it before...

Hung parliament? Rather have a hanged parliament.

I've seen 4" blades for angle grinders that incorporate a chainsaw
chain. They're used for coarse shaping for carvings. In fact, I saw
one in use making a totem pole in Alaska and it really worked well.

I also have seen a 4" disk with extremely coarse carbide crystals on it,
but it was for use in an oscillating saw that just looked like an angle
grinder, and was used more for sanding than for cutting.

A sawblade has individual teeth is so that the debris from the material
being cut can be thrown clear of the next tooth. If the blade cannot
clear itself, there is just friction but no cutting.
In the old days B&D used to do a 5" circular saw blade as a drill
attachment. Can't imagine what it could have been used for, but at least
it wasn't spinning at 10,000 rpm
