What Is A Flexible Sanding Belt & What Are The Benefits Of Using One?

As the name implies, flexible sanding belts are flexible and can curve with the workpiece. For this reason, flexible sanding belts are commonly used to sand circular edges, angles, and round surfaces. Flexible sanding belts are often used to sand things like crankshafts or knife handles. Any piece with uneven surfaces could likely benefit from the use of a flexible belt. The curve a flex belt allows provides for an even finish on uneven surfaces. 

These particular belts are J-weight belts. Abrasives are categorized from A to Y based on weight and flexibility. A-weight belts are the most flexible belts while Y-weight belts are the least flexible. J-weight belts offer the perfect balance between flexibility and a sturdy weight. The J label comes from jeans, because the cloth used for J-weight belts is durable and flexible just like jean fabric.

Why Choose Closed Coat Aluminum Oxide?

Aluminum oxide belts are available in two different coats: closed and open. Open coat sanding belts have less abrasive grain coverage on the surface, which allows residue to fall off the belt. Open coat aluminum oxide works well with softer materials (typically soft woods) where more residue is produced in sanding. Closed coat sanding belts offer 100% abrasive grain coverage, which is great for harder materials like steel, copper, titanium, nickel, and more. These belts are labeled metal working sanding belts, because closed coat aluminum oxide does an excellent job grinding and finishing metal.
