Barnwell 12" 300mm Round Metal Cutting Engineers File - Coarse

A double-cut file has two sets of teeth cut in opposite directions, providing a faster cutting action and a slightly smoother finish for its grit. A single-cut file has one set of teeth and is generally used for finer finishing and softer metals.

This file is designed for general-purpose metal cutting and is suitable for most common metals such as mild steel, aluminum, brass, and copper. It is not recommended for very hard steels, hardened materials, or ceramics.

Always use a file handle securely attached to the tang (the pointed end) of the file. This provides a grip for better control and prevents the tang from injuring your hand if the file slips.

Coarse files have fewer, larger teeth per inch. They are designed for rapid removal of material and are best for initial shaping or removing large imperfections. They will leave a rougher surface than finer files.

Keep the file clean by brushing off debris after each use. Store it properly to avoid rust or damage. Avoid using it on materials it's not designed for or striking it against hard objects.

The round profile is ideal for filing internal curved surfaces, such as the inside of drilled holes, concave shapes, or for creating rounded edges. It is less effective for flat surfaces compared to a flat or half-round file.

Ensure the file is clean and free of debris. Check that you are applying adequate pressure and using the correct filing angle. The file may be dull if used extensively; consider using a file cleaner or replacing the file.

This is common with soft metals. Use a file card or wire brush frequently during use to clear the teeth. Try a file with a coarser cut or a file designed for soft metals if this persists.

This file has a coarse cut, intended for rapid removal. For a smoother finish, follow up with a medium or fine cut file. Ensure you are not applying excessive pressure or using an incorrect angle.
