Files are useful for fine shaping and smoothing wood before sanding, Rasps are useful for rough shaping.
ATM provides an assortment of different files, a single rasp and a series of pneumatic rasp tools.
Note that the pneumatic rotating rasp come in two types: 6mm and 1/4 inch. Use the appropriate tool for the job.
ATM provides these tools for fine tuning and finishing work, not for bulk material removal. If possible, use another tool to cut away as much material before proceeding with the rasps and files.
