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 Disc

The 3M PSA Cloth Disc 348D offers reliable performance with its pressure sensitive adhesive backing. This backing sticks firmly to backup pads or steel platens, making it easy to apply and remove. The model 348D is designed for quick replacement during sanding tasks.

Its adhesive system ensures the disc stays in place on various sanding tools, including disc sanders and random orbital sanders. This feature helps maintain efficiency and reduces downtime on the job.

Durable X-weight Backing

This sanding disc features an X-weight cloth backing, which is highly durable and supports aggressive sanding without tearing. The 18 in x NH size provides a broad surface area for tackling large projects with ease.

The cloth backing also resists edge wear, making the disc last longer even under heavy-duty use. This durability is essential for maintaining consistent sanding quality over time.

Fast Cutting Abrasive

Equipped with 36 X-weight aluminum oxide abrasive, the disc cuts quickly and lasts longer than traditional abrasives. This grade is ideal for grinding and dual action sanding on metal surfaces.

Aluminum oxide's self-fracturing property exposes fresh cutting edges during use, ensuring efficient deburring, blending, and finishing on various metal parts and shapes.

Heat-Resistant Resin Bond

The resin bond on the 3M PSA Cloth Disc 348D protects it from heat damage, extending the disc's lifespan. 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 ensures consistent abrasive performance and prevents premature disc failure.

Convenient Case Packaging

This product comes in a pack of 10 discs per case, making it easy to stock up for ongoing projects. The 18 in x NH format fits standard sanding equipment, ensuring compatibility and convenience.

Having multiple discs on hand reduces interruptions and keeps work progressing smoothly, especially in professional or industrial settings.
