The 10-piece set of 140 mm diamond needle files is an indispensable helper for post-processing 3D prints, finishing resin parts, and grinding hard materials that a common steel file cannot handle. Diamond grit galvanically bonded to a steel core removes supports, seams, and imperfections on prints from PLA, PETG, ABS, nylon, and high-temperature materials such as polycarbonate or carbon fiber composites.

Diamond coating for hard materials

The working part of each file is galvanically coated with fine diamond grit. Diamond is the hardest natural material and can handle materials where a standard steel cut simply slips off or quickly dulls - hardened steel, carbide, tempered glass, ceramics, stone, or composites with carbon and glass fibers.

10 profiles for every detail

The set contains ten different profiles: flat, flat tapered, triangular, square, round, half-round, tongue-shaped, knife-shaped, low triangular, and oval-rounded. This allows you to reach every corner, groove, hole, and radius - whether you are cleaning nozzles, tuning the shape of a print, or finishing molds and tools.

Ideal for post-processing 3D prints

The diamond set is a perfect choice for finishing both FDM and SLA prints. Use it to remove support residues, level layer seams, and true up holes for screws or bearings. Unlike classic files, the diamond coating clogs less with molten plastic because it works with a finer cut - the material is removed gradually, without thermal load.

Grip and ergonomics

The total length of 140 mm and slim knurled handle allow precise fingertip work even in tight spots. The grip remains secure during longer sessions, and the files do not twist or slip. Suitable for modelers, jewelers, watchmakers, and workshop maintenance.

Use on nozzles and hotends

A diamond file is an ideal tool for fine-tuning and cleaning brass or hardened nozzles. It helps remove dried plastic residues, level damaged edges, or slightly adjust the diameter. It is also useful for finishing steel extruder parts and hotend blocks.

Universal workshop tool

The set is useful not only in 3D printing, but also for machining tools, molds, keys, locks, ceramics, or glass. It handles finishing work wherever gentle and precise material removal without thermal influence on the surface is required.

Hard and flexible materials

Diamond grit is one of the few solutions that can handle prints from ASA, carbon-filled materials, or harder grades of flexible filaments. While a common file dulls immediately in abrasive composites, the diamond coating lasts significantly longer.
