FAQ – Diamond Flap Disc K 200 (Fine) for Proxxon Long-Neck Angle Grinder

What is the Diamond Flap Disc K 200 used for?

For precise grinding work on tiles, ceramics, glass, and porcelain stoneware.

The Diamond Flap Disc K 200 was specifically developed for fine grinding on hard and delicate materials such as tiles, ceramics, glass, and porcelain stoneware. It is ideal for smoothing cut edges, removing small irregularities, or finishing surfaces without damaging the glaze.

What grit does the disc have and what is it designed for?

It has a fine grit of K 200 – perfect for fine finishing work.

With its K 200 grit, this disc belongs to the fine finishing category. It ensures ultra-smooth surfaces and allows for precise touch-ups, such as edge smoothing or refining delicate cut surfaces. This results in precise, clean finishes without visible sanding marks.

Does it fit the Proxxon long-neck angle grinder?

Yes, it is precisely designed for it.

The Diamond Flap Disc K 200 features a 9.6 mm bore, making it a perfect fit for the Proxxon long-neck angle grinder. This exact fit ensures secure, centered, and low-vibration mounting—resulting in smooth, precise grinding performance and a long service life for both the disc and the tool.

What is the size of the disc?

It has a diameter of 50 mm.

With a compact 50 mm diameter, the disc allows precise work even in tight spaces and hard-to-reach areas. This makes it particularly suitable for detailed work, edges, curves, and fine finishing tasks in tile or ceramic projects.

What are the advantages of the diamond-coated flaps?

They ensure even material removal and long service life.

The diamond-coated flaps distribute the grinding pressure evenly across the entire surface. This ensures uniform material removal with excellent control. Because diamonds are extremely wear-resistant, the disc maintains high performance and durability over many hours of use.

Does the disc generate much heat while grinding?

No, its special structure minimizes heat buildup.

The flap design effectively reduces friction heat during operation. This protects sensitive tile surfaces, prevents glaze chipping, and reduces the risk of cracks. As a result, even extended grinding sessions can be performed safely and gently on delicate materials.

Can the disc also be used on glass?

Yes, it’s also suitable for glass.

Thanks to its fine diamond coating, the K 200 disc is versatile and can also be used for glasswork. It allows for controlled grinding and deburring of glass edges without overheating or damaging the material, ensuring clean, precise results on glass and glazed surfaces.

How long does the Diamond Flap Disc K 200 last?

It offers a long service life thanks to its diamond coating.

Durability depends on the material, applied pressure, and usage time, but the premium diamond coating ensures significantly longer life than conventional grinding discs. Even with frequent use, it maintains its shape stability and grinding performance over many applications.

What distinguishes the K 200 from coarser discs?

It delivers a finer finish and protects the surface.

Unlike coarse-grit diamond or corundum discs, the K 200 removes less material per pass. This prevents deep scratches and leaves a clean, smooth surface—ideal for final polishing and finishing delicate materials like glazed tiles or ceramics.

Is the disc suitable for beginners?

Yes, it’s easy and safe to handle.

Thanks to its stable mounting, smooth operation, and controllable grinding behavior, the Diamond Flap Disc K 200 is suitable even for less experienced users. It delivers professional results with minimal effort—perfect for both DIY enthusiasts and professionals alike.
