Viila Bahco ERGO 4-187-05-2-2

The Bahco ERGO 4-187-05-2-2 is a triangular taper file designed for precision shaping and finishing. With an extra-slim profile and a narrow 6 mm working width, this triangular file is intended for accurate work in tight spaces and for detailed edges. The second-cut tooth pattern provides efficient material removal while maintaining a controlled, even finish. The file is lightweight at approximately 75 g and features a dual-component ERGO handle that improves grip and control during repetitive or fine operations.

Advantages

The triangular geometry allows access to acute angles and inside corners that flat files cannot reach, while the second-cut surface balances cutting speed and surface quality. The extra-slim taper reduces clogging and enables work on small parts or narrow slots. The dual-component ERGO handle is shaped to reduce hand fatigue and secure the tool during precise movements. Together these features make the file suitable for both professional workshops and hobby applications where accuracy and consistent results are important.

Suitable for

• Shaping and deburring small metal components
• Finishing edges in woodworking and plastic work
• Filing inside corners and acute angles
• Model making, instrument repair, and tool maintenance

Key specifications

• File type: triangular taper file
• Cut pattern: second cut (medium-coarse tooth)
• Working width: 6 mm
• Profile: extra-slim taper
• Handle: dual-component ergonomic handle
• Weight: approx. 75 g

How to use

Secure the workpiece before filing to prevent movement and ensure accurate results. Hold the ERGO handle comfortably and apply steady forward strokes along the file’s length; lift the file on the return stroke to avoid dulling the teeth. Use light to moderate pressure appropriate to the material—softer materials require less force while harder metals may need more controlled, repeated passes. Clean the teeth regularly with a file card or wire brush to maintain cutting performance.

Recommendations

For best results, match the triangular taper file to the profile and material you are working on. Keep the file clean and store it in a dry place to prevent corrosion. When working on precision tasks, use magnification and steady clamping to protect both the workpiece and the file’s cutting edges.
