DIY Frequently Asked Questions / Disc Sander')">
Used mostly for metal sanding or grinding, but also capable of removing stock in plastics, wood or concrete when used with the proper accessory stone, disc or wheel.
Aggressively removes stock but leaves scratches in the material.
Available in two styles: the angle head where the disc runs parallel to the motor, and the vertical style where the disc runs in a plane perpendicular to the motor.
Polishers are another variation of this sander, but they operate at much lower speeds than the sander. A sander should not be used for polishing as the high speed could burn the paint.
