3M™ PSA Cloth Disc 348D 3/4" X NH P240 Grit Aluminum Oxide

Description

3M™ psa cloth disc 348D is a heavy-duty sanding disc that features a high-strength pressure sensitive adhesive backing that adheres to a backup pad or a steel platen for an efficient application and clean removal.

Our 3M™ psa cloth disc 348D features a heat-resistant resin bond and cloth backing that make this sanding disc a good choice for high heat and heavy duty sanding applications. Aluminum oxide particles in a closed coat offer a fast cut for grinding and dual action (d/a) sanding on metal. This versatile disc provides a fast efficient method for deburring blending cleaning up and finishing metal parts and surfaces of various sizes and shapes.

Psa or pressure-sensitive adhesive disc is pressed onto a backup pad (also called a disc pad and sold separately) that is attached to a disc sander random orbital sander or stationary disc sander. We chose aluminum oxide abrasive which is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough durable abrasive that self-fractures to expose fresh cutting edges in use whereas traditional abrasives such as garnet quickly wear down with use.

Due to their fast cut-rate hardness strength and low heat retention they are widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking including ferrous alloys. Heat-resistant resin is a sturdy binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions of high heat or pressure.
