- Curved cut teeth: utilized in the automotive industry for smoothing body panels
Coarseness
American and Swiss hand files offer varying coarseness grades, impacting the finish achieved and material removal rate.
It is important to consider the type of material you are working with when selecting a file cut type. For instance, if you are working with soft materials, a rasp cut file may be more suitable as it will provide a rough finish. On the other hand, if you require a smooth finish, a file with single cut teeth would be the better option.
Additionally, the coarseness of the file will determine how fast material is removed. A coarser file will remove material more quickly but may result in a rougher finish, while a finer file will remove material more slowly but provide a smoother finish.
It is recommended to have a variety of hand files with different cuts and coarseness grades in your toolkit so that you can choose the right one for each specific task. This will ensure that you achieve the best results in your filing work.
