Extra Stiff
KEYSTONE natural-Bristle brushs are Lab and operatory Brushes with natural Bristle (boar/hog hair) bristles, engineered for the specific application of Lab bench polishing — apply polistar emulsion or polishing compound on the bench lathe. Natural Bristle is the long-running Lab standard for charging-and-applying polishing compound on the bench lathe — the bristles hold compound predictably and conform to contoured workpiece surfaces.
Sold in numbered sizes (#0 through #20+) for everything from fine detail work to broad surface application. Standard wood-handle construction; multiple shapes (round, flat, miniature) per the workflow.
