Dymo round file 250 mm, pack of 12 — metalworking hand tool

Round file by Dymo, 250 mm length, supplied as a box of 12 pieces. This metalworking hand tool has a round cross-section designed for enlarging holes, shaping concave surfaces, deburring and finishing cylindrical profiles in metal, wood or plastic. The 250 mm length provides a balance between reach and control, making these files suitable for workshop use, maintenance tasks and detailed shaping where rounded cavities and internal contours require smoothing.

Advantages

The Dymo round file delivers uniform material removal along a curved cutting surface, enabling precise shaping of circular or semi-circular profiles without damaging surrounding areas. Manufactured for consistent tooth pattern and hardness, each file in the pack provides predictable cutting performance and wear resistance. Supplied in a set of 12, the pack is convenient for professional shops or maintenance departments that need multiple tools available for repeated or parallel tasks.

• Enlarging and finishing round holes in metal, wood and plastic

How to use

Select the appropriate round file from the pack and secure the workpiece before starting. Use steady, even strokes in the direction that engages the file teeth—typically pushing away from the body—while maintaining consistent pressure to avoid gouging. Rotate the file within the hole or along the curved surface as needed to achieve uniform material removal. Periodically clear filings from the teeth with a file card or brush to maintain cutting efficiency. For metal work, use light cuts and check fit frequently to prevent over-removal.

Usage recommendations

Wear appropriate eye protection and gloves when filing. Choose a comfortable handle or fit a handle to the tang if one is not already fitted. For fine finishing, follow with finer abrasive or polishing tools to reach the required surface finish.
