Product: DN 8 inch Diamond Coated Triangle File, 200 mm Length, Grit 180 Medium Key benefits Precise shaping and edge work: Triangle profile allows access to tight corners, grooves, and acute angles that flat files cannot reach. Consistent medium material removal: Grit 180 gives a balance between efficient stock removal and a controlled, smooth finish suitable for finishing and prep work. Durable abrasive surface: Diamond coating provides effective cutting on hard, brittle materials commonly used in glass and ceramic work. Easy to control: 200 mm (8 inch) length offers good reach while remaining easy to handle for detailed tasks. Main features Shape: Triangle cross section for three working faces and access to internal corners. Length: 200 mm (8 inch) overall length for comfortable handling and reach. Abrasive: Diamond coated surface for hardness and longlasting cutting action. Grit: 180 medium, intended for general shaping, deburring, and smoothing. What it solves Removes sharp or uneven edges left after cutting glass or tile, reducing chipping during installation. Shapes small pieces and trims corners accurately where power tools are impractical or too aggressive. Smooths and refines cut lines to prepare edges for bonding or finishing. Typical applications Glass fabrication and : Smooth and refine edges of glass shelves, panes, and custom cut pieces prior to assembly. Tile and ceramic finishing: Trim tile edges for a precise fit around fixtures, corners, and trim pieces. Stained glass and hobby work: Shape small glass segments and open seam areas in stained glass projects for accurate fitting. Usage tips Use steady, light strokes to avoid overworking the material and to maintain control. Clean the file surface periodically to remove debris for consistent performance. Store dry to preserve the substrate and coating. Compatibility and suitability Designed primarily for filing glass; also suitable for other hard, brittle materials such as ceramic and tile where medium grit shaping is required. Not intended as a replacement for coarse grinding tools on heavy metal removal tasks. specifics Model identification: DN 8 inch triangle file Size: 200 mm length Grit: 180 medium Coating: Diamond coated cutting surface This tool is appropriate for glassworkers, tile installers, hobbyists, and craftsmen who need precise corner filing and controlled material removal on hard, brittle materials.
