What pitch of a hacksaw blade is typical for general shop use?

1. 24-pitch

2. 18-pitch

3. 14-pitch

4. 12-pitch

The correct answer is: 18-pitch

The pitch of a hacksaw blade refers to the number of teeth per inch. For general shop use, an 18-pitch blade is ideal because it strikes a balance between cutting speed and the quality of the cut. This pitch is suitable for a variety of materials, allowing for efficient cutting while providing a smoother finish than blades with a coarser pitch. An 18-pitch blade has enough teeth to engage with most materials without being so fine that it clogs or moves too slowly, making it versatile for tasks involving metal, plastic, and other common materials in a shop environment. As a result, it is often the go-to choice for general-purpose applications. This balance of versatility and performance makes the 18-pitch blade the most commonly used for everyday tasks in a workshop setting.
