Product Information
Full details
These Magnusson junior hacksaw blades are designed for DIY enthusiasts and professionals needing to make precise cuts on various metals. Their key benefit is the combination of durable high-grade carbon steel construction with a balanced 14 TPI for efficient cutting and a clean finish. A potential caveat is their specific 152mm (6") length, which limits their use to compatible junior hacksaw frames.

FAQs
What does '14 TPI' mean?
TPI stands for 'Teeth Per Inch'. A 14 TPI blade has 14 teeth for every inch of its length, indicating a medium coarseness suitable for general metal cutting.
Can I use these blades with a standard hacksaw?
No, these blades are specifically designed for junior hacksaw frames that accommodate 152mm (6") blades. Standard hacksaws typically require longer blades.
How do I know when to replace the blade?
You should replace the blade when you notice a significant decrease in cutting speed, require excessive force to cut, or if the teeth appear worn, bent, or broken.
Are these blades suitable for cutting wood?
These blades are manufactured for cutting metals. While they might cut through softer woods, they are not optimized for it and will likely dull faster. Use wood-specific blades for wood cutting.
How should I store the unused blades?
Store the unused blades in a clean, dry environment, ideally in their original packaging or a dedicated blade storage case to protect them from moisture and damage.
What is the purpose of the powder-coated finish?
The powder-coated finish provides a layer of protection against corrosion, helping to prevent rust and extend the overall lifespan of the blade, especially when stored or used in humid conditions.
Troubleshooting
Blade breaks during use.
Ensure the blade is properly tensioned in the hacksaw frame. Do not force the cut; let the teeth do the work. Check that you are using the correct blade for the material.
Blade dulls quickly.
The material being cut may be too hard for the blade's specifications. Ensure the teeth are not clogged with debris. Clean the blade regularly.
Rough or uneven cut.
Check blade tension; it may be too loose. Ensure the blade is installed with teeth facing the correct direction (forward). The blade may be nearing the end of its life and requires replacement.
Blade won't stay tensioned.
Inspect the tensioning mechanism on the hacksaw frame for damage or wear. Ensure the blade is correctly seated in the frame's slots.
Pros and Cons
Pros
- Durable construction for extended use.
- Balanced TPI for efficient and clean cuts.
- Corrosion-resistant coating enhances lifespan.

Setup, Compatibility & Care
Setup:
- Ensure your hacksaw frame is a junior hacksaw model designed for 152mm (6") blades.
- Loosen the blade tensioning mechanism on the hacksaw frame.
- Insert one end of the blade into the designated slot at the front of the frame, ensuring the teeth face forward (away from the handle).
- Insert the other end of the blade into the hook at the back of the frame.
- Tension the blade by tightening the mechanism until the blade is taut. A properly tensioned blade will produce a 'ping' sound when plucked.
Compatibility:
- Hacksaw Frame: Compatible *only* with junior hacksaw frames designed to accept 152mm (6") blades.
- Materials: Suitable for cutting most metals, including mild steel, aluminum, copper, brass, and unhardened tool steel or stainless steel. Not recommended for cutting extremely hard metals or materials thicker than the blade's depth capacity.
Care:
- Cleaning: After use, brush off any metal shavings or debris from the blade using a stiff brush. Avoid using water unless absolutely necessary, and dry thoroughly immediately after.
- Storage: Store blades in a dry place, preferably in their original packaging or a blade holder, to prevent rust and damage.
- Replacement: Replace the blade when it becomes dull, teeth are damaged, or cutting performance noticeably degrades. Always ensure the saw is not under tension when changing blades.
