6 Inch 100 Mesh Pro Lapidary Diamond Sanding Disc - Black

Prepare and shape your gemstones with the Ameritool 6 Inch 100 Mesh Pro Lapidary Diamond Sanding Discs (Black)—a coarse-grit solution designed for fast material removal and initial surface leveling on smaller stones. Perfect for the first stage of your lapidary workflow, this disc efficiently removes saw marks, uneven surfaces, and excess material, setting the foundation for smoother grits.

Made with diamond embedded resin bonded to a flexible surface, the 100 mesh grit delivers aggressive yet controlled cutting performance, allowing you to shape and level stones with precision while maintaining control over delicate details.

Built for professional durability, these pro sanding discs outperform standard silicon carbide discs, offering longer life and consistent results across repeated sessions. The pressure-sensitive adhesive (PSA) backing provides quick, secure attachment to Ameritool backing plates, keeping your workflow seamless and efficient.

The black color coding allows for instant grit identification, and the integrated dye system helps you monitor disc life—if the color is still visible, the diamond is actively cutting.

Key Features:

• 6-inch diameter for precise coverage on smaller stones

• 100 mesh (black) for coarse shaping and rapid material removal

• Diamond-embedded resin for long-lasting, consistent performance
