File MODECO MN-65-148 semi-round tungsten 150 mm - hand tool for metal and wood

MODECO MN-65-148 semi-round tungsten file, 150 mm working length, is a hand tool designed for shaping, deburring and finishing edges on metal and wood where a semi-cylindrical profile is required. The file's semi-round cross-section combines a convex surface for creating concave contours and a flat side for leveling and refining flat areas. A tungsten-treated tooth surface increases wear resistance and extends service life compared with untreated files, allowing consistent material removal over repeated use.

Advantages

The tungsten-treated teeth offer improved durability and longer cutting life, reducing the need for frequent replacement. The semi-round profile provides versatility: the curved face is suited for concave and rounded surfaces while the flat side handles straight edges and fine finishing. With a 150 mm working length, the tool balances reach and control for detailed tasks. The hand file construction ensures tactile feedback for precision filing in workshop and hobby applications.

Suitable for

• Shaping and smoothing metal edges and contours
• Creating and finishing concave profiles in wood and soft materials
• Deburring cut edges after sawing, drilling or machining
• General maintenance and repair tasks in workshops and hobby projects

Key specifications

• Working length: 150 mm
• Profile: semi-round (half-round)
• Surface treatment: tungsten (wolfram) teeth/coating for enhanced wear resistance
• Intended materials: metal and wood
• Tool type: hand file for manual filing and finishing

How to use

Secure the workpiece before filing to prevent movement. Use the curved face of the semi-round file for concave areas and internal contours; use the flat side for straight edges and fine finishing passes. Apply steady, even strokes in the cutting direction and avoid excessive pressure to prevent tool clogging or uneven removal. Periodically clean the teeth with a file card or brush to maintain cutting efficiency. For metal work, check progress frequently and adjust strokes to achieve the required surface tolerance.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match the file profile and tooth coarseness to the material and task: finer passes for finishing, coarser strokes for rapid material removal. Store the file in a dry place and avoid contact with other tools to preserve the tungsten-treated surface.
