Questions about this item

Does the 180 grit Flex-Hone wear out and need replacement?

Yes, the 180 grit abrasive on the BC5818 Flex-Hone gradually wears down with use and will eventually require a new hone to maintain cutting performance.

What limits continuous use of the 5/8 inch Flex-Hone first?

Heat buildup in the workpiece and abrasive loading are the first limits during sustained honing with the 180 grit BC5818.
