SOLUTION

The four basic types of file cuts are:

1. Single Cut:

   • One set of parallel teeth cut diagonally across the face of the file.
   • Used for finishing work and achieving a smoother surface.

2. Double Cut:

   • Two sets of teeth cut at an angle to each other, creating a criss-cross pattern.
   • Removes material more aggressively than single-cut files.

3. Rasp Cut:

   • Individual, sharp, pointed teeth that protrude from the file surface.
   • Used for roughing and shaping, especially on softer materials like wood.

4. Curved Cut:

   • Teeth are cut in a curved pattern, creating a deeper cutting action.
   • Often used for removing material from softer metals.
