SSP Polydia Diamond Disc – 22mm, Medium #200 Grit, Brown

Achieve controlled grinding and surface refinement on porcelain, metal, and mineral materials with the SSP Polydia 22mm Diamond Disc. This highly flexible, diamond-impregnated plastic disc combines efficient abrasive action with the flexibility needed to follow contours and work across shaped surfaces.

The brown disc is the medium #200 grit in the Polydia system, making it a versatile intermediate choice for refining surfaces after coarser grinding and before moving to finer grades. Its 22mm diameter provides a useful working area for jewelry, metalsmithing, dental laboratory, and other precision finishing applications.

The disc is supplied HP mounted, ready for use with an appropriate compatible handpiece or rotary system.

Specifications

The #200 grit is worth adding to the Micro-Tools listing. Your existing page identifies the disc only as “Brown-middle,” while SSP's catalog specifically identifies Polydia 1200 as #200, medium, brown.

Flexible Diamond Abrasive Disc

Unlike a rigid grinding wheel, the Polydia Disc is highly flexible. SSP manufactures it from a diamond-impregnated plastic material designed for grinding porcelain, metals, and mineral materials.

That flexibility is valuable when working on:

• Curved surfaces
• Contoured components
• Irregular shapes
• Edges and transitions
• Detailed metalwork
• Precision finishing applications

The disc can conform more readily to the shape of the workpiece than a rigid abrasive, providing greater control when refining complex surfaces.

Medium #200 Grit

The brown Polydia Disc is the #200 medium grade in SSP's four-step Polydia abrasive range.

Medium grit makes this disc particularly useful when a surface needs additional refinement after coarse grinding but isn't yet ready for fine finishing.

It provides a useful balance between material removal and surface refinement for many precision grinding operations.

Designed for Porcelain, Metal & Minerals

SSP specifically identifies Polydia discs for grinding:

• Porcelain
• Metal
• Minerals

That broad material range makes Polydia useful for professionals working across jewelry, metalsmithing, laboratory, technical, and other precision applications.

Excellent for Metal Finishing

The combination of diamond abrasive and a flexible backing makes the Polydia system particularly useful for shaped metal surfaces.

Rather than relying solely on a rigid abrasive, the flexible disc can follow contours as you work, making it useful for refining areas where maintaining the underlying form is important.

For jewelry and metalsmithing applications, that can include curved components, sculptural forms, edges, and other detailed surfaces.

Useful for Porcelain & Hard Materials

Diamond abrasive is also well suited to hard materials that can be challenging for conventional abrasives.

SSP specifically includes porcelain among the intended materials for the Polydia Disc, making this a useful precision abrasive where controlled grinding of porcelain surfaces is required.

Part of the Polydia Grit System

This is where I would make the Micro-Tools listings much more useful.

SSP's 22mm Polydia system consists of four clearly identified abrasive grades:

That progression gives customers an easy way to select the appropriate disc for the stage of finishing they're performing.

Brown Medium Disc – #200

The brown #200 disc sits between the green coarse and yellow fine grades.

Choose it when you need:

• More refinement than the #120 coarse disc
• More cutting action than the #400 fine disc
• Intermediate surface preparation
• Controlled removal of grinding marks
• A transition between coarse shaping and finer finishing

For a multi-step finishing process, the color coding makes it easy to identify the correct grade at the bench.

Highly Flexible Construction

Flexibility is one of the defining features of the Polydia system.

The thin, flexible abrasive surface can adapt to the shape of the workpiece, which is particularly helpful when the goal is to refine an existing contour rather than grind it with a rigid wheel.

This makes Polydia discs useful for detailed work where control over the finished geometry matters.

HP Mounted

The Polydia Disc is supplied HP mounted, eliminating the need to purchase and install the abrasive disc on a separate mandrel before use.

This makes it a convenient, purpose-built rotary abrasive for precision bench work.

Ideal For

The SSP Polydia 22mm Medium Diamond Disc is an excellent choice for:

• Jewelry making
• Jewelry finishing
• Metalsmithing
• Metal surface refinement
• Porcelain grinding
• Mineral materials
• Precision grinding
• Contoured surfaces
• Detailed finishing
• Laboratory work
• Professional bench work

Frequently Asked Questions
