●[Polishing finished]: Use to remove firescale, strong cleaning, pre-polishing, texturizing and polishing. ●[Unique and Exquisite Design]:Open design dissipates heat unlike rubber wheels. Bonded Cubitron mineral abrasive is much harder than most metals. ●[LESS PRESSURE & PERFECT PARTS]:Flexible bristles require less pressure than wire brushes and conform to contours even with complex parts. The bristle spacing is ideal for removing coatings and other highly stressed substances. ●[Multipurpose]:The radial bristle brush is an idea for metalworking, paint preparation, coating and corrosion removal, and works well on aluminum, brass and bronze. ●[Flexible and Safe]:The detail sanding brushes have very flexible bristles that allow the removal of the outer "surface layer" without damaging the base layer underneath.
