The teeth of a file are formed by cuts made on its face. Files have cuts of different types.

Types of cut:

Basically, there are four types: Single cut, Double cut, Rasp cut, and Curved cut.

Single cut File:

• A single cut file has rows of teeth cut in one direction across its face.
• The teeth are at an angle of 60° to the centre line.
• It can cut chips as wide as the cut of the file.
• Files with this cut are useful for filing soft metals like brass, aluminium, bronze, and copper. 

Double cut file:

• A double cut file has two rows of teeth cut diagonal to each other.
• The first row of teeth is known as OVERCUT and they are cut at an angle of 70°.
• The other cut, made diagonal to this, is known as UPCUT. and is at an angle of 51°.
• This removes stock faster than the single cut file.

Rasp Cut File:

• The rasp cut has individual, sharp, pointed teeth in a line, and is useful for filing wood, leather and other soft materials.
• These files are available only in half round shape.

Curved cut file:

• These files have deeper cutting action and are useful for filing soft materials like- aluminium, tin, copper, and plastic.
• The curved cut files are available only in a flat shape.
