Miniature Cross Hole Deburring System
Abrasive Nylon Twisted-in-Wire brushes are an excellent solution to mild surface finishing and thread deburring.
For diameters over 4mm, the Flex-Hone® is a faster, more efficient solution for finishing and crosshole deburring. Flex-Hones are not recommended for threaded applications.
