Sanding discs are commonly attached to random orbital sanders via hook and loop, and are simply circular cuts of sandpaper built to withstand the rigors of motorized application. Sandpaper discs that have holes in them are intended to collect dust through the holes when used with compatible random orbital sanders, and is a popular combination. The quality of your sanding disc determines how effective your tool can sand through a material, durability and how often you have to replace a disc (read: long term cost), dust collection efficiency, print quality (can you read what grit it is?), and the finish quality on the product you are sanding.
A potent combination of cost and productivity that is the preferred muscle on most woodworking projects.
- Very effective material removal. $0.50/gram of material (Wood Magazine)
- Great cost comparative to competition
- Stearate coated discs mitigate clogging/capturing dust on the disc surface
- Some prefer discs that aren’t as hard or durable as these are for final finishing.
Durability and efficiency at a price.
- Very effective material removal
- Very durable
- Very effective dust collection and does not clog easily
- Comparatively expensive
