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