Foredom 2'' Sanding Disc Ao Psa 220 Grit

Description:

The 2" Sanding Disc AO PSA 220 Grit is a precision finishing tool engineered for consistent fine-grade surface refinement within dental laboratory environments. Constructed from durable aluminum oxide abrasive grains, it offers reliable cutting action while maintaining delicate control, making it ideal for smoothing, pre-polishing, and refining the surface texture of various restorative materials. This disc is particularly useful for finishing dental alloys, zirconia frameworks, ceramic substructures, acrylic prosthetics, and thermoplastic appliances. The 220-grit rating provides a balanced level of abrasion, making it effective for removing minor irregularities, reducing fine scratches, and preparing surfaces for finer polishing steps or pumice finishing. Its controlled cutting action preserves anatomical details and avoids over-reduction. The PSA (Pressure-Sensitive Adhesive) backing ensures quick installation onto disc mandrels or sanding pads, offering secure adhesion during rotational use. This eliminates slippage, improves operator control, and enhances precision during detailed contouring and surface refining. The 2" diameter provides excellent handling for both broad surfaces and focused adjustments. The disc maintains cool operation, minimizing the risk of thermal damage to ceramics, acrylics, or composite materials. It resists clogging and offers consistent performance even during extended use, contributing to a smooth, uninterrupted workflow in the dental laboratory. Overall, the 2" Sanding Disc AO PSA 220 Grit is an essential finishing accessory that supports high-quality craftsmanship, delivering uniform abrasion, dependable control, and a refined surface ready for final polishing stages.
