SureWerx 553606 JET 3-1/2 x 5/8-11NC Knot Banded Cup Brush - High Performance - Model Number CKB3201T

JET knot banded wire cup brushes are similar to a regular knot style cup brush but have the added feature of a band or knock-off ring. This ring helps to eliminate brush flare out, keeping brush tips in contact with the workpiece for a more aggressive brushing action. As the exposed brush wears down to the ring, it is easily knocked off to expose the balance of the wire for increased brush life. An excellent safety and performance aid, the band helps to reduce wire breakage caused by flare out * 553607 and 553606 Feature exclusive larger diameter high density knot twisted brushes for 5" and 6" grinders - The industry’s most productive brushes for this grinder range
