Here is a polishing tip from @littleoscilla - “If I need to get into hard to reach places but I don't have a fine-pointed bullet burr, I put the silicone polishing bit in my flex shaft and slide it along a file to create the point I need!” Shaping and reshaping these kinds of flex shaft bits is something I constantly do! Thank you so much for taking the time to share with us Emily! #polishingjewelry #flexshaft #polishingbits
