Red Seal Welding Practice Exam

How is the length of a file measured?

1. Measuring from the tip to the heel

2. Measuring the cutting edge only

3. Measuring from handle to tip

4. Measuring from one side to the other

The correct answer is: Measuring from the tip to the heel

When it comes to measuring the length of a file, it is important to understand that the length is not determined by simply measuring from one side to the other. This option (D) may provide overall dimensions, but it does not capture the full length of the file. Similarly, measuring from the cutting edge (B) or from the handle to the tip (C) will also not give an accurate measurement. Instead, the true length of a file is measured from the tip to the heel, which encompasses the entire working area of the file. This method allows for a precise measurement and ensures that you are using the correct size file for your task.
