Foredom Edm Abrasive Stone 400 Grit Filer

Description:

The EDM Abrasive Stone 400 Grit is a fine-grade finishing stone used in dental laboratories for high-precision surface refinement. As part of a reciprocating filer assembly, this stone allows technicians to achieve smooth, delicate finishes on ceramics, metals, and composite restorations. It plays a crucial role during the final contouring stages, where precision and surface quality directly influence the appearance and fit of the restoration. The 400-grit texture provides gentle abrasive action, enabling removal of minor irregularities without altering the overall shape or dimensions of the prosthesis. It is ideal for smoothing margins, adjusting contact surfaces, refining occlusal details, and preparing ceramic surfaces before glazing or polishing. The stone�s fine abrasive structure minimizes scratch depth, leaving surfaces clean and uniform. Manufactured for durability and stability, the stone resists breaking, glazing, and excessive wear even under repeated reciprocating motion. This ensures consistent performance and helps maintain predictable results in delicate finishing tasks. The stone integrates securely into filer systems, producing controlled, precise movement that prevents over-reduction. Dental technicians commonly use this stone when finalizing veneers, crowns, implant abutments, orthodontic appliances, and ceramic frameworks. Its fine finishing ability enhances marginal integrity, surface smoothness, and overall aesthetic outcome of the restoration. By offering excellent control and refined abrasion, the EDM Abrasive Stone 400 Grit is indispensable in achieving the high-quality surfaces required for modern dental prosthetics.
