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.

Trusted 3M PSA Model

With a size of 18 in x 14 in, the disc covers a large surface area, making it suitable for various sanding jobs. The cloth backing also helps maintain the disc’s shape during use, improving sanding consistency.

Effective Aluminum Oxide Abrasive

The 80 X-weight grade of aluminum oxide abrasive cuts fast and lasts long, making it ideal for many surfaces. This abrasive mineral self-fractures to expose fresh edges, ensuring continuous cutting efficiency.

It works well on metal and woodworking materials, providing a fast, efficient method for deburring, blending, and finishing. The abrasive’s versatility makes it a popular choice among professionals.

Heat-Resistant Resin Bond

The disc features a resin bond that protects it from heat damage, extending its life during heavy sanding. This heat resistance is crucial for applications that generate high temperatures, preventing premature wear.

This sturdy bond keeps the abrasive firmly attached to the backing even under pressure, ensuring stable performance. It’s especially useful in demanding tasks where heat buildup is common.

Convenient Pack Size Case

Each case contains 10 discs, providing enough supply for multiple projects or extended use. The pack size helps professionals maintain stock and reduce downtime by having replacements ready.

The 18 in x 14 in disc format fits standard backup pads and sanders, making it compatible with various tools. This size and pack count balance convenience and value for users.
