What are hacksaw blades used for?

Hacksaw blades are designed for cutting metal, plastic and other tough materials using a manual hacksaw frame. They are commonly used for cutting steel pipe, bolts, threaded rod, aluminium profiles and PVC pipe where controlled, accurate cutting is required.

What hacksaw blade is best for cutting metal?

For cutting metal, bi-metal hacksaw blades with around 18–24 teeth per inch (TPI) are usually the best choice. These blades combine flexibility with hardened teeth, allowing them to cut steel, copper pipe, aluminium and other metals while resisting breakage.

Can hacksaw blades cut stainless steel?

Yes. Stainless steel can be cut using high-quality hacksaw blades with a higher tooth count, typically 24–32 TPI. Fine tooth blades provide smoother cutting and reduce wear when working with harder metals such as stainless steel pipe or sheet.

What are junior hacksaw blades used for?

Junior hacksaw blades are shorter blades designed for compact hacksaw frames. They are ideal for cutting small metal parts, plastic pipe and materials in tight spaces where a full-size hacksaw cannot easily reach.

How do I choose the right hacksaw blade TPI?

The correct teeth-per-inch (TPI) depends on the material being cut. Lower TPI blades cut faster in thicker materials, while higher TPI blades produce smoother cuts in thin metal or stainless steel. For general metal cutting, 24 TPI is often a good all-round choice.
