Foredom 2'' Ao Sandpaper Disc Screw-Lok 320 Grit

Description:

The 2'' AO Sandpaper Disc Screw-Lok 320 Grit is a high-quality ultra-fine abrasive engineered for advanced finishing stages in dental laboratory production. Designed to deliver controlled, delicate abrasion, this disc is essential when technicians require perfectly refined surfaces before executing final polishing procedures. Its premium aluminum oxide abrasive structure provides a consistent fine-cut action suitable for finishing acrylic denture bases, PMMA provisional restorations, orthodontic appliances, implant hybrid prosthetics, and metal frameworks. The 320-grit texture removes extremely shallow scratches, allowing the disc to create smooth, even surfaces that significantly reduce polishing time while improving the final shine and texture. The Screw-Lok attachment system ensures secure, stable engagement with handpieces, eliminating disc slippage or wobble during high-speed finishing. This stability is crucial when working around delicate contour areas such as marginal ridges, interproximal anatomy, thin flange edges, retention notches, and connector transitions. This grit level is typically used after 240-grit abrasives in a multi-step surface refinement workflow. It produces a clean, soft, satin-like finish that prepares restorations for pumice polishing, silicone wheels, or final high-shine systems. Because it removes minimal material, it is safe for use on thin structures where maintaining anatomy is critical. The 2'' diameter offers an ideal balance between coverage and maneuverability, allowing technicians to work efficiently on broad surfaces while retaining the precision needed for detailed refinements. The disc�s durable aluminum oxide composition ensures long-lasting performance even under continuous daily use in busy prosthetic, orthodontic, and implant laboratories. Whether used for smoothing transitional contours on dentures, refining edges on clear aligners, or preparing metal surfaces for high-shine buffing, the 320-grit AO Screw-Lok disc is a reliable and essential tool for achieving refined, polished, high-quality dental restorations.
