So you think your favorite industrial or personal sanders.
Sandpaper Basics and Degrees of Coarseness
* In woodworking aluminum oxide grit are used. Aluminum grit is also useful due to its resilience to heat. For that reason it can be used in some metalwork.
* The coarseness of the sleeve depends on the grit number. The higher the number, the more fine it will be. For example, 80 grit or less is more course.
* The material on which the sandpaper rests will also make a difference. Flexible materials work best for uneven surfaces. The speed of the sanding will increase depending on the hardness of the material.
* Cloth is used as a backing for sander belts and discs.
* There's a difference between closed coat abrasives. The space between grains on open coat abrasives is wider. That being said, you will notice that open coat abrasives do not sand through as quickly and that makes them ideal for power sanding.
Tips On Using Sanding Sleeves
* Don't over use the paper. Once it's dull it will be no good to you. Replace the sleeve often.
* If you start with a course sanding sleeve try your best to work your way up to the finest grit you intend to use. A fast jump from course to fine won't give you positive results.
* If you want to sand something that requires both fine and course gritting, you can mount half of each type onto the sanding drum.
