Alpha Ceramica Buff Polishing Disc – 4 in., Hook & Loop
Alpha Ceramica Buff Polishing Disc – 4 in., Hook & Loop
The Alpha Ceramica Buff Polishing Disc is a 4 in. hook-and-loop final buffing disc that takes a polished granite edge to a deep gloss. Alpha builds it by heat-compressing tin oxide and aluminum oxide powders with a natural fiber into a flexible disc, so no polishing compound or chemical is needed at the bench. Alpha rates it to 4,000 max RPM and prints the grit as "Buff" rather than a number.
It is a final buff, not a polishing step — it will not remove a scratch or a saw mark. Run the Alpha Ceramica Resin Wet Polishing Disc sequence first. Alpha also notes that, unlike the rest of the Ceramica line, a large amount of water is not required here.

Frequently Asked Questions
What is the difference between the black and the white disc?
Alpha supplies black for dark stones and white for light-colored stones. Alpha states that the black buff is the disc that will bring up the shine on black granites, and that using black and white in sequence gives an especially high gloss. Both are variants on this listing.
Does it need water?
Alpha notes that, unlike the rest of the Ceramica line, a large amount of water is not required for the Buff disc.
What grit is it?
Alpha prints the grit for this disc as "Buff" rather than a number — it is a final polishing step, not a point in the grit sequence.
Do I still need polishing compound?
Alpha states that the powders normally used for final polishing are already compressed into the disc, so no separate chemical is necessary to reach a high final polish.
What is the maximum speed?
Alpha rates the Ceramica Buff disc to 4,000 max RPM.
