Hack Saw Blade
A fine-toothed blade mounted in a hack saw frame for cutting metal and plastic.
What is it?
The hacksaw blade is a thin strip of hardened steel with teeth cut on one edge, tensioned in a frame to cut metal and plastic. Teeth per inch (TPI) and pitch are matched to the material.
What is it used for?
- Cutting metal rod and tube
- Cutting thin sheet and plastic
- Precision metal cutting with control
How to choose
Match TPI to material thickness: 24 TPI for thin metal and conduit, 18 for general steel, 32 for thin tubing. A bi-metal blade resists breakage.
Anatomy
Understanding the parts of a hack saw blade helps you use, maintain, and buy it with confidence.
- Body: the main working portion of the tool
- Working end: the part that contacts the material
- Handle: the part you grip for control and leverage
Materials & construction
Quality hack saw blades are made from hardened, heat-treated steel (often chrome-vanadium or high-carbon) chosen for strength, edge retention, and resistance to wear and corrosion.
Safety & maintenance
- Wear safety glasses; metal chips and fragments are sharp
- Use the correct technique and pressure for the material
- Keep the tool clean and store it safely
- Fit a handle where the tool uses one to protect your hand
