What Are Resin Fiber Discs Used For?

Getting Familiar With Resin Fiber Discs

Resin fiber discs are tough flat sanding discs that have layers of fiber -- which is used as a backing. The fiber has resin coated over it which will help to minimize issues when it comes to sanding or the finish on the material -- for example, grain stripping or loading. 

What are Fiber Discs Used For

When looking for a heavy stock removal, fiber discs are for you. Fiber discs come in different grits, however, they have a single layer of grit which can shorten the life and usage of it. Once the discs no longer has a sharp edge, it is time for a new one.

Which Disc is Right For You

When choosing which disc to purchase, a zirconia or ceramic material has a self sharpening grain -- giving it a cleaner/cooler cut.

Things to Consider When Using a Resin Fiber Disc

When using a resin fiber disc, try to not use too much pressure on one spot for too long. If you are dealing with a larger surface, try using a motion such as sweeping to avoid being in an area for too long. Another thing to consider is airflow. Using something to create airflow between discs and a backup pad will help with the heat. The reason you want to avoid heating/overheating is that it will damage the surface you are working on while also shortening the discs life span.
