Product Details
Dual diameter spin-grit brushes are designed for the effective removal of soft and light scale deposits from straight, ferrous, and nonferrous internally enhanced tubes. The kit includes brushes with a large diameter end that cleans into the grooves and a small diameter end that cleans the lands of a tube's rifling, suitable for tubes with an inner diameter ranging from 1" to 1-1/4" (25-32mm). It is important to note that ESGB brushes require a #TCB-C coupling to connect to GTC-720, GTC-721, GTC-721G, and GTC-821 flexible shafts, with one coupling provided with each brush order.
