Thanks to all who replied to my query, I found what I wanted at
CARBATEC. Its a wood grinding blade for an angle grinder, goes real
well, even in our local hardwood (red gum)
Theres 2 of them, coarse and fine. Haven't bought the fine one yet.
$19 each......cheap enough to give it a try. An oxymoron - a cheap
tool that works!!

For those interested, heres the catalog link (hope this works)
