- Jet’s 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.
