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.

With this backing, the disc withstands heavy use and maintains its shape, which helps deliver consistent results. The 3-inch diameter and NH arbor size fit many standard sanders, enhancing versatility on the job.

Fast Cutting Aluminum Oxide

The disc features aluminum oxide abrasive, known for its fast cutting ability and long life. This mineral self-fractures during use, exposing fresh cutting edges that keep the disc effective over time.

Aluminum oxide works well on various surfaces, especially metal, making the 3M PSA Cloth Disc 348D a great choice for grinding, deburring, and finishing metal parts efficiently.

Heat-Resistant Resin Bond

A heat-resistant resin bond protects the disc from heat damage during sanding. This bond keeps the abrasive firmly attached to the backing, even under high pressure and temperature.

This feature extends the disc’s life and maintains performance in heavy-duty applications. The resin bond also supports both wet and dry sanding, adding to the disc’s versatility.

Convenient Pack Size Case

The product comes in a pack of 50 discs per pack, with 200 discs per case. This large quantity supports ongoing projects and reduces downtime by ensuring you have enough discs on hand.
