Additional information

The Professional Standard for Radial Disc Finishing

The Dedeco 7/8″ radial disc is considered the benchmark size for most finishing applications.

It provides enough surface area to work efficiently on flat and curved surfaces, while still offering the control needed for detailed work. For many users, this is the only size required for the majority of tasks.

Why Choose the 7/8″ Size?

Balanced Performance

Combines surface coverage with precision, making it suitable for a wide range of applications.

Consistent Control

Ideal peripheral speed for micromotors and flexible shaft machines.

Flexible Setup

Can be used as a single disc or stacked to create a wider polishing head

Designed for Stacking & Versatility

The 7/8″ format works particularly well when stacked on an MM503 mandrel.
