3M Diamond Files-4 Piece Set Medium Grit 74 Microns

The 3M Flexible Diamond File Set delivers consistent, precise material removal for jewelers and metalsmiths working with hard materials, including hardened steel, carbide, ceramics, glass, and gemstones. Each set includes 4 color-coded red files in a medium grit of 74 microns, offering an effective balance between stock removal and surface refinement. The flexible diamond-coated surface conforms slightly to workpiece contours, making these files well suited for detailed bench work and hard-to-reach areas.

The set includes four distinct profiles — two flat files, one half-round file, and one narrow flat file — covering a range of filing tasks from broad surface work to tight grooves and curved surfaces. Made in England by 3M, these files are a reliable addition to any professional jeweler's bench.
