Disc sanders are typically employed to sand or grind metals, woods or concrete. Disc sanders that offer high RPM (rotations per minute) ratings are ideal for applications that involve polishing or paint removal. Disc sander manufacturers offer a large selection of different types of disc sanders. There are advantages and disadvantages associated with each type of disc sander.
There are currently two styles of disc sanders on the market, the angled-head disc sander and the vertical style disc sander, according to Aubuchon Hardware. On an angled-head disc sander, the disc operates parallel to the disc sander's motor. On a vertical style disc sander, the disc operates on a plane perpendicular to the motor.
Several companies, including Klutch, Rikon, Craftsman and Makita, manufacture disc sanders. Consumers can purchase stationary or hand-operated disc sanders for £32 to £260. According to NexTag.com, Klutch offers a 12-inch, 1-horsepower disc sander for around £97. Rikon offers a 12-inch, bench-top disc sander for around £130. Craftsman manufactures a 6-inch disc sander that doubles as a belt sander for about £84. Makita's 5-inch disc sander is available for around £39.
Many disc sanders offer several features making them more attractive to consumers. Stationary disk sanders usually come equipped with adjustable tables allowing for angular sanding, according to Technology Student. Locking nuts can be released and tightened for adjustments. Disc sanders that are bolted to tables must feature emergency stop buttons for safety. These disc sanders can usually be turned “on” and “off” with foot switches.
Care should be taken while removing paint with disc sanders. Using a disc sander to remove lead paint may cause lead to become airborne. Lead poisoning can lead to brain or nervous disorders, high blood pressure, a decrease in red blood count and possibly death. Smaller children are more susceptible to lead poisoning.
Safety equipment should be worn at all times while working with disc sanders, according to Technology Student. Goggles can prevent chips or dust from damaging a person's eyes. To prevent injury to the fingers, hands should be kept at a safe distance from rotating parts of disc sanders. Some models have guards to prevent bodily harm while operating them. Dust collection systems keep dust from contaminating a workplace.
