Metal file triangular MODECO MN-66-145 250 mm Friendly Grip

The MODECO Metal File triangular MN-66-145 with a 250 mm working length and Friendly Grip handle is a hand tool designed for precise filing and deburring of metal edges, grooves and corners. Its triangular cross-section provides three cutting faces that reach internal angles and tight spaces, making it suitable for finishing and shaping tasks where access and control are required. The Friendly Grip handle offers improved hold during prolonged work, reducing slippage while maintaining control of filing direction and pressure.

Advantages

The triangular shape gives three flat, sharp faces for effective material removal in internal angles and narrow slots. The 250 mm working length balances reach and leverage for controlled strokes on metal parts. The Friendly Grip handle is ergonomically shaped to reduce hand fatigue and enhance grip stability. The hardened steel filing surface provides consistent cutting performance and a predictable tooth pattern for uniform finishing.

Suitable for

• Deburring and smoothing sharp edges on metal sheets and profiles
• Shaping and enlarging internal corners and grooves
• Precision metalwork in workshops and maintenance tasks
• Hobby metalworking and model making that requires fine finishing

Key specifications

• File shape: triangular cross-section with three working faces
• Working length: 250 mm
• Handle: ergonomically contoured Friendly Grip for slip resistance
• Material: hardened steel filing surface for durable cutting edges
• Intended use: manual filing and deburring of ferrous and non-ferrous metals

How to use

Secure the workpiece in a vise or clamp to prevent movement. Hold the file by the Friendly Grip handle and apply steady, even strokes along the workpiece in the direction of the cutting teeth; lift the file on the return stroke if the tooth pattern requires it. Use the appropriate face of the triangular file to access internal angles or narrow grooves. Apply light to moderate pressure and check progress frequently to avoid over-removal of material and to maintain the desired profile.

Usage recommendations

For best results, clean the file teeth regularly with a wire brush or file card to prevent clogging and reduce chatter. Match file coarseness to the task: use coarser teeth for rapid stock removal and finer teeth for finishing passes. Wear appropriate personal protective equipment, such as gloves and eye protection, when filing metal.
