Fast Cutting Double-Sided Dental Laboratory Diamond Disc

The plaster disc diamond is an essential tool designed specifically for dental laboratory use.

With its large 45mm diameter, this professional grade diamond disc cuts through dental plaster and stone models with ease.

The flat surface prevents deflection while grinding, allowing smooth surfacing of dies for precision restorations.

The thin 0.3mm thickness enables detailed trimming of models and fine finishing of dental prosthetics.

The double-sided disc maintains cutting efficiency twice as long as single-sided alternatives.

Running at high speeds up to 30,000 rpm, this disc saves significant time grinding and polishing.

Dental technicians will appreciate the high performance and time savings of this disc for efficient plaster removal.

It’s a must-have plaster disc tool for prosthodontics, implants, orthodontics and other dentistry procedures requiring accurate models.
