Red Seal Welding Practice Exam

What should the saw blade pitch be for cutting aluminum?

1. 14 pitch

2. 20 pitch

3. 32 pitch

4. 40 pitch

The correct answer is: 14 pitch

Different saw blade pitches are suitable for different materials. When cutting aluminum, it is important to choose a saw blade with a low pitch, such as 14 pitch. This is because aluminum is a soft metal and requires a finer blade with more teeth to make precise cuts. Having a higher pitch, such as 20, 32, or 40, could result in rough or jagged cuts. Therefore, options B, C, and D are incorrect for cutting aluminum.
