Proxxon – Brass Wheel Brushes, 5 Pcs., 7/8″

Brass Brushes. Ideal for surface cleaning on brass and brass alloys, copper, precious and semi-precious metals, stainless steel, semi-precious stones, plastic and wood. Acid resistant and electrically neutral, thus suitable for working with electronic components. All shanks 2.35mm (3/32″). Note: Permit the brushes to work only with gentle contact pressure and at the recommended rotational speed! If the pressure is too high, the individual wires will be bent too strongly and afterwards straighten up again due to the centrifugal force. This excessive flexural fatigue stress of the wires on their seating promotes the notch effect. They are prone to breakage!
