Foredom 2'' Ao Sandpaper Disc Screw-Lok 40 Grit

Description:

2'' AO Sandpaper Disc Screw-Lok 40 Grit is a robust medium-coarse abrasive engineered to provide efficient material reduction with greater control and smoother cutting than ultra-coarse grits. Its aluminum oxide abrasive surface ensures consistent performance during demanding dental laboratory tasks involving acrylics, metal frameworks, and orthodontic materials. This disc is particularly useful for trimming denture bases, reducing thick resin areas, shaping provisional restorations, adjusting clasp arms, shaping occlusal surfaces on processed appliances, and removing casting sprues. It strikes a practical balance between aggressive removal and manageable refinement, making it a preferred choice during the transition from heavy debulking to intermediate shaping. The Screw-Lok attachment ensures a firm, vibration-free connection to dental handpieces. This stability improves accuracy and user control, especially when working on delicate contouring areas where excessive vibration could compromise anatomical detail. The secure locking mechanism allows the disc to operate reliably under moderate to high pressure. Its 40-grit composition is ideal for situations that require rapid yet precise shaping. Unlike the extremely coarse 24-grit disc, this grit creates smoother scratch patterns, allowing technicians to refine surfaces without deep scoring. This reduces the need for excessive intermediate finishing and improves workflow efficiency. Constructed with durable aluminum oxide, the disc withstands continuous rotational use and maintains its cutting quality over time. Its 2'' diameter provides excellent coverage for trimming broad areas while maintaining versatility for smaller restorative details. Widely used in denture fabrication, crown-and-bridge finishing, orthodontic appliance adjustment, and implant prosthesis shaping, the AO 40-grit Screw-Lok disc supports reliable, predictable results in early-stage finishing workflows. Its combination of durability, cutting efficiency, and control makes it an indispensable tool in any dental laboratory.
