Original MK End Brushes - Hard 3/8"L x 3/16" Diameter

Featuring a longer bristle length of 0.37 inches (approximately 9.52 mm), these hard end brushes provide extra reach for deep-set components and hollow jewelry designs. The 0.18 inch diameter allows for focused cleaning power, ensuring that the jeweler can apply concentrated pressure to a specific spot. These are particularly effective for reaching the bottom of tall bezel settings or cleaning out the interior of heavy-walled tubing during fabrication. The hard bristle grade ensures that the brush remains aggressive enough to drive polishing compounds into the metal for a consistent and professional result.
