Cup Brush, NG Tools NGCB4M14

These 4” crimped cup brushes are designed with a small diameter so they can be used in small, compact places or on irregular work pieces. The 4 inch brass coated cup brush is affixed with a a ¼” hex shank allowing for higher torque and can be attached to an Impact Driver, Die Grinder, or Power Drill. The brass coating helps to minimize corrosion and prevents rust of the steel bristles even after multiple uses. It also makes the wire tougher and more flexible which further extends the life of the brush and creates a superior price to performance ratio.
