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 is designed for heavy-duty sanding tasks. This model features a high-strength pressure sensitive adhesive backing that sticks firmly to backup pads or steel platens, ensuring efficient use and quick replacement.

Its pressure sensitive adhesive system allows for clean removal without residue, making it ideal for applications requiring frequent disc changes. The 348D model is trusted for its reliable performance in various sanding setups.

Durable X-Weight Backing

This sanding disc uses an 80 X-weight cloth backing, which supports aggressive sanding without tearing or edge wear. The durable cloth backing extends the disc's life, even under tough conditions.

Fast Cutting Abrasive

Aluminum oxide abrasive is the core material in this disc, known for its fast cutting ability and long lifespan. The 80 grit grade offers a balance of aggressive material removal and surface finish quality.

This abrasive is suitable for both woodworking and metalworking, including ferrous alloys. Its self-fracturing property exposes fresh cutting edges, maintaining performance throughout the sanding process.

Heat-Resistant Resin Bond

The resin bond in the 3M PSA Cloth Disc 348D protects the abrasive from heat damage, which extends the disc's usable life. This feature is especially important during heavy-duty sanding where heat buildup is common.

By maintaining bond stability under high heat and pressure, the resin bond ensures consistent sanding results. This makes the disc a reliable choice for demanding applications requiring durability and performance.
