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 Brand

The 3M PSA Cloth Disc 348D is a reliable sanding solution from 3M, known for quality abrasives. This model features a pressure sensitive adhesive (PSA) backing that sticks firmly to backup pads or steel platens for efficient use.

Its high-strength adhesive allows quick and clean removal, making disc replacement fast and hassle-free. This ensures minimal downtime during sanding tasks, improving overall productivity.

Durable 40 X-weight Backing

This sanding disc uses a 40 X-weight cloth backing, which is tough enough to handle aggressive sanding without tearing or edge wear. The durable cloth supports heavy-duty applications, extending the disc's usable life.

Such backing is ideal for demanding jobs where strength and flexibility are needed, allowing the disc to conform to various surfaces while maintaining integrity during use.

Precise 3 Inch Size

The disc measures 3 inches in diameter with a NH (non-hole) format, making it compatible with many disc sanders. This size is versatile for detailed work and fits well on random orbital and stationary sanders.

Its compact dimensions allow for easy handling and control, especially when working on metal parts or surfaces of different shapes and sizes.

Heat-Resistant Resin Bond

Featuring a resin bond that resists heat damage, this disc maintains performance even under high temperatures. This bond protects the abrasive particles and backing, extending the disc's lifespan during heavy sanding.

Such heat resistance is crucial for metalworking tasks where friction can generate significant heat, ensuring consistent cutting and finishing quality.

Bulk 50 Pack Case

The 3M PSA Cloth Disc 348D comes in a convenient pack of 50 discs per case, providing ample supply for ongoing projects. This bulk packaging reduces the need for frequent reordering and supports continuous work.

Having 200 discs per case overall means you can stock up for large-scale operations or multiple job sites, ensuring you always have the right abrasive ready.
