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.

3M PSA Cloth Disc

The 3M PSA Cloth Disc 348D offers reliable performance with its pressure sensitive adhesive backing. This feature allows the disc to stick firmly to a backup pad or steel platen, ensuring efficient sanding and easy removal when it's time to replace it.

Durable X-weight Backing

This sanding disc features a 50 X-weight cloth backing that provides durability and strength. The cloth backing supports aggressive applications without tearing or edge wear, extending the disc's usability in demanding conditions.

With this backing, the disc withstands heavy use on various surfaces, making it suitable for both metalworking and woodworking tasks. The 12 inch size fits many standard sanding tools, offering versatility in application.

Aluminum Oxide Abrasive

Equipped with aluminum oxide abrasive, the 3M PSA Cloth Disc 348D cuts fast and lasts long. This abrasive is known for its toughness and ability to self-fracture, exposing fresh cutting edges during use for consistent performance.

The abrasive is arranged in a closed coat, which enhances grinding and dual action sanding on metal surfaces. This makes the disc a great choice for deburring, blending, and finishing metal parts efficiently.

Heat-Resistant Resin Bond

The disc uses a resin bond that protects it from heat damage, extending its life during high-temperature sanding tasks. This bond maintains stability even under pressure, ensuring the abrasive stays firmly attached to the backing.

This heat resistance makes the 348D model suitable for heavy-duty sanding where heat buildup is common. It performs well in both wet and dry applications, adding to its versatility across different work environments.
