What is the first step in cutting tubing with a hacksaw?

The appropriate choice of a hacksaw blade for cutting tubing is critical for achieving a clean and efficient cut. Choosing a blade with 32 teeth per inch is ideal for this task because it strikes a balance between being fine enough to provide a smooth cut while still having enough tooth strength to effectively cut through metal tubing.

A blade with too few teeth, such as one that has 18 teeth per inch, may remove material too aggressively, leading to a rough finish and potential damage to the tubing. Conversely, selecting a blade with too many teeth, like a blade with 40 teeth per inch, might result in clogging and overheating, as more resistance is met from the material being cut. Overall, a blade with 32 teeth per inch is the most efficient choice for cutting tubing, as it allows for better control and produces a more precise cut without compromising the integrity of the material.
