A hacksaw is a hand saw that holds a blade under tension in a frame. The blade must be selected based on the material you intend to cut.
Typical applications
- Hacksaw selection starts with the material and the workpiece. The blade must suit the material; no single blade is specified for every job.
Advantages
- The frame holds the blade under tension, and the blade must remain rigid while the frame is correctly aligned. These conditions are required for proper operation, but they do not establish a comparative cutting‑speed advantage.
Specifications to check
- Selection advice: check blade compatibility, frame size and tooth spacing against the intended material and stock. Teeth per inch describes tooth spacing, not blade length.
Limitations
- Excessive blade pressure can cause breakage. A hacksaw with a blade loose in its frame must not be used.
Buying considerations
Check the material and stock size before selecting a hacksaw and blade. Match the blade to the task and consult the exact tool instructions. This guide does not provide a universal blade size.
Safety & limits
- Wear safety glasses or goggles. Keep the work firmly supported. Do not twist the blade while applying pressure, or continue with a loose blade.
