Best Grinding Discs?

...or slow down the speed.....they should only be doing well under 2000 for heavy grinding, I run mine at 1400 with 36 grit.

Landlubber --what the hell is your avatar, I cant make out what it is , is it a woolly mammoth with a hat on near your bedroom window?

I don't know what the hell that is.

4 inch 16 grit 4000 RPM the skill is in your hand not the machine.

16 grit is like self cleaning, like a mud tyre, it self cleans.

...Frosty, have a look here, the "real" Landlubber...poor bugger has no "real" boat, this is what happens when you only have a dinghy, no more ocean boats to play with....don't let this happen to you.

I don't know what you are smoking but I would give it up if I were you.

Im a sensative boy, I will be having night mares now after looking at those distorted figures.

Change your avatar to a crankshaft or something nice, as long as its not a cute kitten or i'lle have to smash my lap top in.

Just thought I should follow-up and say that the Zec is the deal. About twice as fast as regular 16 grit disc and no problems chopping up the surface - just hold it flat. One wheel did the whole job too so no lost time changing discs. I did follow with the 36 grit soft pad on buffer to finesse it a little. Not the tool for every grinding application but if you need aggressive material removal this is it. Thanks to all.

Dear CDK: Where do you buy the diamond segment grinding disc? Thanks, Roy

Roy, this is the kind of disc designed for cutting relatively soft but abrasive materials like limestone or marble. I bought mine in a department store a few years ago. It came as a set of 3 different discs, the others for ceramic tiles and granite.

You should have no problem buying such discs on Ebay.
