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.
