Brownells .410 Bore Fine Chamber Flex Hone, Light Blue

Mounted on a flexible shaft, hundreds of abrasive "balls" offer an efficient and straightforward method for cleaning and polishing barrels, whether they are older or new. For used barrels, starting with the fine hone and following with the fine effectively eliminates rough and tight spots, resulting in a bright, tangible finish. Simply running a patch through the barrel before and after honing reveals the remarkable improvement. During honing, any tight spots can be identified and smoothed out with additional attention. For new barrels, using the fine hone alone enhances the factory finish to a stunning, mirror-bright appearance that is sure to please customers. The process is simple - secure the hone in a variable speed electric drill, apply Flex Hone oil, 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, aiding the cutting action. Fine grit refers to 800 grit aluminum oxide Fine chamber Flex-Hone with light blue tip
