SSP Polydia Diamond Disc 22mm – #800 Extra Fine, Red-Brown
Achieve controlled, extra-fine surface finishing with the SSP Polydia 22mm Diamond Disc. This highly flexible, diamond-impregnated plastic disc is designed for precision grinding and finishing of porcelain, metal, and mineral materials, making it an excellent choice for detailed work where access and surface control are important.
This red-brown Polydia disc is the extra-fine #800 grade, the finest grit in the four-step Polydia range. Its flexible construction allows the disc to follow contours and reach areas that can be difficult to finish with rigid abrasive tools.

Extra-Fine #800 Surface Finishing
The #800 extra-fine grade is designed for the finest stage of the Polydia abrasive sequence.
It removes significantly less material than the coarser Polydia grades, making it particularly useful when the goal is to refine an already-shaped surface, reduce the scratch pattern left by previous abrasive steps, and prepare the work for subsequent finishing or polishing.
Flexible Diamond-Impregnated Disc
Unlike a rigid grinding wheel, the Polydia disc is made from a highly flexible diamond-impregnated plastic material.
This flexibility allows the abrasive surface to conform more readily to contours and shaped surfaces, giving you greater control when working on detailed pieces and areas that are difficult to approach with rigid abrasive tools.
For Porcelain, Metal & Mineral Materials
Polydia discs are designed for surface finishing on:
-
Porcelain
-
Metal
-
Mineral materials
The diamond abrasive makes the disc particularly useful for precision work on hard materials where controlled surface refinement is required.
Color-Coded Polydia Grit System
SSP Polydia discs use a simple color-coded system to identify each abrasive grade:
| Color | Grit | Grade |
|---|---|---|
| Green | #120 | Coarse |
| Brown | #200 | Medium |
| Yellow | #400 | Fine |
| Red-Brown | #800 | Extra Fine |
The red-brown #800 disc is the finest grade in the series and is ideal for the final abrasive stage when working progressively through the Polydia system.

Frequently Asked Questions
What grit is the red-brown Polydia disc?
The red-brown disc is #800 grit, the extra-fine grade in the Polydia series.
What is the diameter of the disc?
The disc measures 22mm in diameter.
What is Polydia made for?
Polydia discs are designed for precision grinding and surface finishing of porcelain, metal, and mineral materials.
Does the disc contain diamond abrasive?
Yes. Polydia is a diamond-impregnated flexible plastic abrasive disc.
Is this a rigid diamond disc?
No. One of the primary features of the Polydia system is its highly flexible disc construction, which helps the abrasive follow contours and shaped surfaces.
Where does #800 fit in the Polydia grit sequence?
#800 is the extra-fine and finest grade in the four-disc Polydia sequence: #120 coarse, #200 medium, #400 fine, and #800 extra fine.
Which Polydia disc should I use before this one?
For progressive finishing, the yellow #400 fine Polydia disc is the next coarser grade before the red-brown #800 extra-fine disc.
Is the disc mounted?
Yes. The manufacturer specifies the Polydia disc as HP mounted, so it is supplied mounted for use with a compatible handpiece.
Is this primarily for heavy material removal?
No. The #800 extra-fine grade is better suited to fine surface refinement and finishing. For more aggressive material removal, choose one of the coarser Polydia grades.
