Metal grinding help wanted

[ukdodger]

Hi, Just popped in here to ask if anyone knows where I can get hold of an internal metal die grinding wheel about 25-30mm diameter. Stone wheels which are aplenty leave a residue which blunts my thread cutting machine. I've trolled the net without success.

Thanks
Roger

Have you tried rotary burrs?

Thanks Robot. Just what I wanted. So that's what they're called. Buy yourself a pint my friend.

Cheers
