FAQs
What materials can these blades cut?
These blades are suitable for cutting a variety of materials, including metal, wood, and plastic.
How long do the blades last?
Blade life depends on the material being cut and the frequency of use. Proper care can extend blade life.
How do I choose the right TPI?
Use a lower TPI (e.g., 18) for softer materials and thicker cuts, and a higher TPI (e.g., 32) for harder materials and thinner cuts. The 24 TPI blades are a good middle ground.
How do I install the blade?
Insert the blade into the hacksaw frame with the teeth pointing in the direction of the cut. Tighten the blade securely.
Can I use these blades on power tools?
These blades are designed for use with manual hacksaws. Do not use with power tools.
What is the blade length?
The blade length is 300mm (12 inches).
What is the benefit of the bi-metal construction?
Bi-metal construction, with Weldtec technology, makes the blade shatterproof and provides durability.
Troubleshooting
Blade is not cutting effectively.
Check the blade's teeth for damage and replace if necessary. Ensure the blade is installed correctly with the teeth facing the right direction. Use the appropriate TPI for the material.
Blade is breaking.
Reduce pressure when cutting. Make sure the blade is installed tightly. Consider using a blade with a higher TPI for thinner materials.
Blade is bending.
