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 a reliable sanding solution with its pressure sensitive adhesive backing. This feature allows the disc to stick firmly to a backup pad or steel platen, making it easy to apply and remove for quick replacement.

Designed for efficiency, this model ensures clean removal without residue, helping you maintain productivity. The 3M brand guarantees quality and performance in heavy-duty sanding tasks.

Durable X-Weight Backing

This sanding disc uses an X-weight cloth backing that supports aggressive applications without tearing or edge wear. This durability is essential for tough jobs where the disc must withstand heavy use.

With an 8 inch diameter and NH die 800L format, the disc fits common sanding tools, making it versatile for various metalworking and woodworking projects.

Fast Cutting Aluminum Oxide

Aluminum oxide abrasive is chosen for its fast cutting ability and long life. This mineral self-fractures to expose fresh edges, providing consistent performance throughout the disc’s use.

The 40 X-weight grade ensures a balance between aggressive cutting and durability, ideal for deburring, blending, and finishing metal parts efficiently.

Heat-Resistant Resin Bond

The resin bond on this disc protects it from heat damage, extending its lifespan during heavy-duty sanding. This heat resistance is crucial when working on tasks that generate high temperatures.

This feature helps maintain the bond stability between abrasive and backing, ensuring the disc performs well in both wet and dry applications without degrading prematurely.

Pack Size And Format

The 3M PSA Cloth Disc 348D comes in a pack of 50 discs per carton and 250 discs per case. This quantity supports large projects or ongoing industrial use without frequent reordering.

Its format, 8 in x NH die 800L, fits standard sanding equipment, making it easy to integrate into existing workflows for metal and woodworking tasks.
