Brownells .410 Bore Fine Bore Flex Hone, Light Blue

Hundreds of abrasive "balls" are mounted on a flexible shaft, providing the most efficient and straightforward method for cleaning and polishing older barrels or achieving a mirror finish on new ones. For used barrels, utilizing the fine hone, followed by the Fine, effectively removes rough and tight spots, resulting in a bright finish that is both visible and tangible. It is recommended to run a patch through the barrel before and after honing to observe the remarkable difference. During the honing process, tight spots can be detected and addressed with additional attention until they are smoothed out. For new barrels, the fine hone alone is sufficient to enhance the factory finish to a stunning, mirror-bright appearance that is sure to satisfy customers. The process is simple - secure the hone in a variable speed electric drill, apply Flex Hone oil to the hone, start the drill and insert the hone into the barrel from the breech end, if possible. As the hone operates, a slurry of abrasive and oil forms, facilitating the cutting action. Fine grit refers to 800 grit aluminum oxide Fine bore flex hone with light blue tip
