Refine Printed Surfaces with Precision After supports are removed, small marks, sharp edges, or layer artifacts may remain on printed parts. Needle files allow controlled material removal to smooth edges, refine surfaces, and improve the final finish. Reach Areas Sandpaper Can’t Narrow slots, internal corners, and small holes are often difficult to finish with sandpaper. The slim file profile makes it easier to reach tight spaces and refine intricate features with precision. Four File Shapes for Different Features The set includes flat, round, half-round, and triangular files for working on flat surfaces, curved areas, narrow grooves, and internal corners. This makes it easier to handle different printed geometries with the right tool. Fine Teeth for Controlled Material Removal Made from durable T12A steel, the fine-tooth pattern supports gradual, controlled material removal. It is well suited for refining PLA, PETG, ABS, and other common 3D printing materials. Basic Information Included Files Flat, Half-Round, Triangular，Round Handle PVC non-slip Surface Sandblasted Effective Filing Length 63 ± 2 mm Overall Length 140 ± 2 mm Tooth Density Fine teeth (240 grit), ~23 teeth per cm Consideration Material Limitations: Not suitable for hard alloys or fiberglass. Safety: Wear goggles when working on harder materials to avoid injury from chipped teeth.
