Engineers File Set - 5 Piece - 200mm

While they will cut wood, it is not recommended. Wood fibers can clog the fine teeth quickly, and wood-specific rasps are much more efficient for that material.

Use the flat file for flat surfaces, the round for holes or curves, the half-round for concave surfaces, the triangular for corners, and the square for slots.

Engineers files are hardened and typically cannot be re-sharpened effectively; it is better to clean them regularly to maintain performance.

Yes, they are compatible with steel, but be aware that stainless steel is harder than mild steel and will cause the files to wear down faster.

Use a file card (a specific brush with stiff metal bristles) to scrub the teeth in the direction of the cut.

The teeth are likely clogged with metal shavings. Use a file card or stiff wire brush to clean the debris from between the teeth.

Ensure the tang is fully seated in the handle. If it remains loose, check for debris inside the handle socket or contact the retailer for a replacement if the handle is defective.
