Triangular File 175 x 10 mm MEGA model 69512

MEGA Triangular File 175 x 10 mm model 69512 is a hand file with a tapered triangular cross-section designed for manual metalworking and woodworking. With nominal dimensions of 175 x 10 mm, this tool is intended for filing internal angles, narrow slots and for shaping or sharpening saw teeth. The compact length and narrow profile make it suitable for precision finishing, deburring and correcting small joins in repair, hobby and workshop tasks.

Advantages

The triangular profile provides three cutting faces that reach into corners and V-grooves more effectively than flat files. Its tapered geometry allows controlled material removal along the length of the file, enabling accurate shaping and edge work. The hand file's size balances access to confined spaces with sufficient cutting surface for repeated use. The product is straightforward to handle for one-handed or two-handed operations and is compatible with common manual filing techniques.

Suitable for

• Filing internal angles and V-grooves in metal and softwood
• Sharpening and setting saw teeth
• Deburring edges after cutting or machining
• Shaping small profiles and correcting joints in repair and hobby projects
• Cleaning out slots, keyways and narrow recesses

Key specifications

How to use

Secure the workpiece in a vise or clamp to prevent movement. Hold the file by the handle or the heel with one hand and guide the tip with the other for stability. Use long, even strokes away from your body, applying light to moderate pressure on the forward stroke and easing pressure on the return stroke to preserve the teeth. Work gradually, checking fit and profile frequently to avoid over‑filing. Clean the file teeth periodically with a file card or wire brush to maintain cutting efficiency.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves when filing. Match file grade and tooth coarseness to the material and the level of removal required; finer teeth for finishing and coarser teeth for rapid material removal. Store the file in a dry place and avoid contact with other tools to protect the cutting edges.
