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, ensuring efficient use and easy removal when replacing discs.

Designed for heavy-duty applications, the 3M brand ensures quality and durability. The model 348D is built to handle tough sanding tasks while maintaining strong adhesion for consistent performance.

Durable X-weight Backing

This sanding disc uses an X-weight cloth backing, which supports aggressive sanding without tearing or edge wear. The durable cloth backing extends the disc’s life, making it suitable for demanding jobs.

The 3-inch size and NH format make it compatible with various sanding tools. This backing strength helps maintain the disc’s shape and effectiveness during use, especially in heavy-duty environments.

Fast Cutting Abrasive

Featuring aluminum oxide abrasive, the disc cuts quickly and lasts longer than many alternatives. This mineral is known for its toughness and ability to self-fracture, exposing fresh cutting edges for continuous efficiency.

With a P120 grade, the disc is ideal for grinding, deburring, and finishing metal surfaces. Its versatility makes it a practical choice for both woodworking and metalworking applications.

Heat-Resistant Resin Bond

The resin bond on this disc protects it from heat damage, which helps extend its lifespan during heavy sanding tasks. This heat resistance ensures the abrasive stays firmly attached even under high pressure and temperature.

This feature is especially useful for applications involving metal parts where heat buildup is common. The resin bond maintains stability, allowing for consistent sanding performance over time.

Size And Pack Count

The disc measures 3 inches in diameter and comes in a pack of 50 pieces, with 200 discs per case. This size fits many standard sanders, making it a convenient choice for various projects.

Having a large pack count ensures you have enough discs for extended use or multiple jobs. The NH format and die 300V specification also contribute to its compatibility with different sanding equipment.
