Essential Support for Every Job

3M™ Fibre Disc Back-up Pads are an essential tool for sanding, deburring, and finishing jobs. These pads provide sturdy support for fibre backed discs, which enhances the power of the abrasive.

Our TN Quick Change attachment system makes it easy to change the pads, while still providing a strong hold. The pads are made of a tough plastic material, which gives support evenly across the surface of the disc.

These hard density back-up pads are strong yet still slightly flexible, which allows for smooth application of abrasive discs to metal surfaces. With 3M™ Fibre Disc Back-up Pads, you can be sure that you have the support you need for every job.
