Brushes are made from animal hair, nylon, and brass. Brushes are available from coarse to soft. Brushes come in three shapes: cup, wheel, and end. They are available in many sizes. Brushes are the most common way of driving diamond compound. Cup brushes are used to diamond corners and flat surfaces. Wheel brushes are used in inside diameters, side walls, parting lines, radii, and round pins. End brushes are used on flat or lightly curved surfaces. Brushes are driven with die or pencil grinders, right angle, and 45 degree angle heads. Light pressure and slow speeds, 2000 to 3000 RPM, are recommended.
