Self-adhesive backing pads allow small discs of abrasive to be attached to a holder and grinding, polishing can easily be achieved on flat surfaces. The abrasive discs have sticky side which is peeled off the discs which are applied to the surface of the disc holder. This is a secure way to attach abrasive discs to a holder – this is a very cheap system as Abrasive discs are cheap but quick and easy to use.
Types of Abrasive Disc Holders:
Rubber Disc Holders – most popular
These flexible disc holders allow much more cushion when polishing and sanding so there is less risk of digging in if the disc is not held at the right angle.
Hard Plastic Disc Holders
Hard Disc holders are more rigid, so a higher pressure can be created between the abrasive and the metal surface. This will create a harder more aggressive cutting and grinding performance. A harder disc will also ensure a surface will be flatter as any bumps will not be cushioned.
Foam Faced Abrasive Disc Holders
Very Flexible Abradisc holders with a layer of foam are useful when you need to conform to a slight rounded profile or concave or convex surface but also keeps flat grinding. It will create a softer grinding effect and no risk of digging into the surface.
