Sandpaper Selection

Sanding a workpiece smooth requires using pro- gressively smaller grit sandpaper until the desired finish is attained.

The abrasiveness of sandpaper is designated in grit size—the larger the number, the finer the abrasive and the smaller the scratches. Thus, 100 grit is finer than 60 grit.

Typically, sanding operations start with a coarse grit and progressively work through the finer (larger number) grits until the desired finish is achieved. Avoid skipping a grit to achieve the best results.

Choosing the correct grits involve many factors, such as the workpiece condition, type/hardness, and the desired finish.

There are many types of sanding belts and discs to choose from. We recommend Aluminum Oxide for general workshop environments. Below is a chart that groups abrasives into different classes and shows which grits fall into each class.
