Trusted 3M Brand Model

The 3M Floor Surfacing Discs 21021 offer reliable performance from a well-known brand. This model is designed to meet professional standards with consistent quality and durability.

Using the 3M 21021 discs ensures you get a trusted product that fits various floor surfacing needs. The brand's reputation supports confidence in every case of 500 discs supplied.

Precise Size And Dimensions

Each disc measures 5 inches in diameter and 0.25 inches thick, providing a balanced size for effective floor surfacing. The 6 slots and 0.5 inch length add to the disc’s flexibility and cutting ability.

This size is ideal for many floor surfacing machines, allowing for efficient coverage and smooth operation. The dimensions help maintain control and precision during use.

Durable Grade And Grit

The discs feature a 36 grit rating, which is coarse enough for fast cutting while still delivering a quality finish. This grade is suitable for removing old finishes and preparing floors for refinishing.

With this grit, the discs last longer and maintain sharpness, reducing the need for frequent replacements. It’s a practical choice for both professional and heavy-duty applications.

Flexible Backing Technology

These surfacing discs use a tough, flexible paper or combination backing that supports durability and adaptability. This backing helps the discs conform to floor contours for better contact and finish.

The flexible backing also contributes to the discs running cooler during use, which extends their life and improves safety. It’s a key feature for maintaining performance over time.

Bulk Pack Saves Time

Sold in a case of 500, these discs provide a large supply that reduces downtime for reordering. Having a bulk pack on hand is convenient for busy job sites and ongoing projects.

This quantity supports continuous work without interruption, making it easier to manage inventory and costs. The case format is practical for storage and transport.
