Foredom 2'' Ao Sandpaper Disc Screw-Lok 400 Grit

Description:

2'' AO Sandpaper Disc Screw-Lok 400 Grit is a premium ultra-fine abrasive disc tailored for expert-level surface refinement in dental laboratories. With its precise 400-grit texture, it provides extremely fine smoothing that prepares restorations for the final polishing stage with exceptional consistency and minimal effort. Manufactured using high-grade aluminum oxide abrasive, this disc delivers a controlled, soft-cut action suitable for finishing acrylic dentures, reshaping provisional crowns and bridges, smoothing edges of orthodontic retainers, refining implant bar structures, and preparing metal frameworks for polishing compounds. Unlike coarser abrasives, the 400-grit disc removes only micro-imperfections, preserving intricate anatomical detail and maintaining critical contours. The Screw-Lok attachment ensures a secure, vibration-free connection to polishing handpieces. This enhances operator precision, especially when working on fragile areas such as incisal edges, occlusal grooves, thin acrylic flanges, or delicate clasps. The improved stability also reduces user fatigue and ensures predictable finishing results. In a structured finishing workflow, the 400-grit disc is typically used after 320-grit and before the transition to pumice, silicone polishers, or high-luster polishing wheels. It provides a satin-smooth finish with minimal scratch patterns, significantly enhancing the final gloss on both acrylic and metal restorations. The 2'' size supports efficient coverage of broad denture surfaces while still allowing effective control in tighter anatomical regions. Aluminum oxide ensures long disc life, resistance to wear, and consistent texturing even during extended laboratory use. Overall, the 400-grit AO Sandpaper Disc Screw-Lok is an outstanding tool for technicians who require precision finishing, stable performance, and beautifully prepared surfaces ready for final polishing. It plays an essential role in achieving esthetically superior, functional, and comfortable dental restorations.
