Ceramic 60 to 120
Zirconia 100 to 240 grit
Al Oxide 150 to 400 Grit
Topcoat(lubricant layer) 40 to 120 Grit
Mirco Finishing (Trizact) A45 (800#) to A6 (2000#) surface texture eg. Scotchbrite medium to superfine polishing (used with applied polish eg. Hyrin for stainless) super cut ceramic (3m cubitron) so efficient it can remove metal in form of steel wool.

It can take as little as 6 seconds and aligning new belt is not fussy as it will zip back into perfect alignment on start up.

Oiling is not required for Radius Master Belt Grinders as all bearing are sealed ball races. The only maintenance necessary is to keep the Radius Master guard swivels suitably adjusted to hold their position for safety reasons. Remember to dust off your Radius Master machine and keep inside of guards clean to prevent a possible smouldering fire.

Yes! Radius Master Belt Grinders are suitable for small, accurate model making as small components can be made on the tool rest with excellent control on the belt edge often removing the need for time consuming milling operations.
