Pack-12 Supra MK 5/8" Soft Natural Bristle Brushes-Unmounted With 1/8" Hole

Supra MK 5/8" Soft Natural Bristle Brushes are premium unmounted miniature brushes designed for professional jewelers and metalsmiths who demand consistent, reliable performance in fine finishing work. These brushes are made in the USA with solid steel ring construction, ensuring long-lasting durability through repeated use. Brush filaments are permanently anchored in the solid steel ring and uniformly distributed for even, predictable wear across the entire brush face.

The soft natural animal hair bristles are ideal for polishing flat, curved, small, and hard-to-reach surfaces where larger brushes cannot perform effectively. The 5/8" diameter provides excellent coverage for detailed work, and the unmounted design allows for flexible use with compatible hub adapters and screw mandrels.

Each brush features a 1/8" diameter center hole for use with hub adapters or screw mandrels fitted with 1/8" diameter screws. Note: Using these brushes with 3/32" diameter screw mandrels will result in a loose, sloppy fit. If you require 3/32" hole brushes, those are also available separately.

Sold by the dozen.

Supra does not manufacture extra soft bristle brushes. Extra soft bristle brushes are produced in China.
