Square File Abraboro Pilnik kwadratowy 250 ABRABORO — metal hand file, 250 mm length

Abraboro Pilnik kwadratowy 250 is a square metal hand file with a 250 mm length designed for shaping, deburring and finishing square and angular profiles. Manufactured by Abraboro, this square-file geometry delivers controlled material removal on edges, inside corners and slots. The file is compatible with standard handles, making it suitable for handheld use in workshops and hobby environments. Its medium profile tooth pattern balances cutting speed and surface finish for use on wood, non-ferrous metals and soft steels.

Advantages

The square cross-section enables precise work on corners, keyways and rectangular slots where flat or round files cannot reach. The 250 mm length offers a compromise between reach and control, allowing stable strokes and access to moderate-depth slots. A medium tooth pattern provides predictable material removal while producing a relatively smooth surface without excessive clogging when used on wood and softer metals.

Suitable for

• Shaping and smoothing square edges and internal corners
• Deburring cut metal and wooden profiles
• Fitting and adjusting rectangular slots, keyways and mortises
• General workshop metalworking and woodworking tasks

Key specifications

• Shape: square cross-section for four-sided filing
• Working length: 250 mm
• Material: hardened steel filing surface suitable for wood, non-ferrous metals and soft steels
• Tooth profile: medium-cut for balanced removal and finish
• Compatibility: fits standard file handles

How to use

Secure the workpiece before filing to prevent movement. Fit an appropriate handle to the tang for safe grip. Use even, full-length strokes away from the body, applying consistent pressure on the forward stroke and lighter pressure on the return stroke when using a single-cut or double-cut file as appropriate. Orient the flat faces and edges of the square file into corners and slots to remove material gradually and check fit frequently to avoid over-filing. Clean the file teeth periodically with a file card or brush to maintain cutting efficiency.

Usage recommendations

For best results, start with coarse shaping using a suitable coarse file or abrasive, then refine with the Abraboro Pilnik kwadratowy 250 to achieve the required dimensions and surface finish. Use light lubricant when filing non-ferrous metals to reduce clogging, and always wear eye protection and gloves when filing.
