Mini Sanding Disc 19.1mm 240g

Grit: P240
Inside Diameter: Ø1.2mm
Outside Diameter: Ø19.1mm

This Mini Sanding Disc is a high-performance precision accessory designed for the final refinement of intricate workpieces. Featuring a compact 19.1mm (3/4") diameter and a 240-grit (240G) abrasive surface, it provides an ultra-fine finish that is essential for high-end craft and restoration projects. Specifically optimized for high-speed rotary tools, this disc allows for meticulous surface smoothing in confined spaces and complex geometries where larger sanding tools would be too aggressive or cumbersome.

The 240-grit rating represents a very fine abrasive grade, making it the ideal choice for "pre-polish" stages or between-coat sanding. On wooden projects, it is perfect for removing the microscopic fuzz (grain raise) that occurs after wetting or sealing, resulting in a surface that feels like glass. For metalworkers and jewelers, it serves as an excellent tool for removing light surface oxidation and blending fine scratches into a uniform, satin-matte finish before transitioning to buffing compounds.

Durability and consistency are at the core of this disc’s design. The abrasive grains are evenly distributed and securely bonded to a resilient backing that resists tearing and heat-induced deformation at high RPMs. This specialized coating is engineered to minimize "loading"—the buildup of dust and debris—ensuring that the disc maintains its cutting efficiency throughout its lifespan. Its small footprint allows the user to apply light, targeted pressure, which is vital when working with delicate veneers or thin-walled 3D prints.

Whether you are perfecting the finish on a custom musical instrument, smoothing a miniature architectural model, or prepping a precision-machined part for a final coat of lacquer, the 240G mini sanding disc delivers professional-grade clarity. It bridges the gap between functional sanding and aesthetic polishing, providing the surgical control required for high-definition craftsmanship.
