Product Information
Full details
This Charnwood bandsaw blade is designed for woodworkers seeking efficient and precise cutting across various wood types, including nail-embedded wood, non-ferrous metals, plastics, and acrylics. Its key benefit is enhanced durability and cutting performance due to its spring-tempered high carbon steel and induction re-hardened teeth. A potential caveat is its specific length (2240mm), requiring compatibility with bandsaws of that precise dimension. It offers decreased production times, a better surface finish, increased fatigue resistance, and longer blade life.

FAQs
What types of wood can this blade cut?
This blade is designed for all types of wood, including nail-embedded wood, as well as non-ferrous metals, plastics, and acrylics.
What is the advantage of ground teeth?
Ground teeth ensure precision cutting, leading to a better surface finish on the workpiece and minimizing material waste due to a narrower kerf.
Can the teeth be resharpened?
Yes, the teeth on this blade can be re-ground, re-shaped, and re-set, allowing for extended blade life and a lower cost per cut.
What bandsaw models is this blade compatible with?
It is compatible with Charnwood models B300, W721 & W720, Sealey SM1305, SIP 01548, Woodstar SB12, Fox F28-191, Draper BS315, Warco BS312, and Metabo BAS317, or similar bandsaws requiring a 2240mm x 1/2" blade.
What makes the teeth so durable?
The teeth are induction re-hardened to 62HRC, which provides exceptional hardness, leading to increased fatigue resistance and a longer sharp edge life.
How should I maintain the blade to prevent rust?
Keep the blade clean and store it in a dry environment. Applying a light coat of oil can help protect it from rust.
Troubleshooting
Blade is not cutting straight
Check blade tension, ensure blade guides are properly aligned and adjusted, and verify the blade is not damaged or twisted.
Blade is dulling quickly
Ensure proper blade tension and speed are used for the material being cut. Clean pitch/resin buildup regularly. Consider if the material is harder than recommended for this blade's typical use.
Blade is breaking
Verify blade tension is not excessively high. Ensure the blade is tracking correctly on the wheels and not rubbing against the wheel rims. Check for nicks or damage on the blade body.
Blade slipping on wheels
Check blade tension; it may be too low. Ensure the bandsaw wheels are clean and free of debris.
Pros and Cons
Pros
- Significantly increased cutting speed compared to standard blades.
- Excellent surface finish on cut materials.
- Extended blade sharpness and durability due to hardened teeth.
- Lower cost per cut over the blade's lifespan due to re-sharpening capability.
- Suitable for a wide range of materials, including challenging ones like nail-embedded wood.
Cons
- Specific blade length (2240mm) requires a compatible bandsaw.
- May require more frequent resharpening/re-setting if used extensively on very hard materials or with significant nail contact.
- Requires proper setup and tensioning on the bandsaw for optimal performance.
- High carbon steel, while durable, can be more susceptible to rust than stainless steel if not maintained.
Setup, Compatibility & Care
Setup:
- Ensure your bandsaw is turned off and unplugged before installing the blade.
- Fit the blade onto the bandsaw wheels, ensuring the teeth are pointing forward (away from the operator).
- Apply the correct tension to the blade as recommended by your bandsaw manufacturer. Proper tension is critical for straight cuts and blade life.
- Align the blade to track correctly on the bandsaw wheels using the guides.
Compatibility:
This blade has a length of 2240mm (88-3/16") and a width of 13mm (1/2"). It is designed for use with Charnwood models B300, W721 & W720, or similar bandsaws requiring this specific blade length and width. It is also compatible with:
- Sealey SM1305
- SIP 01548
- Woodstar SB12
- Fox F28-191
- Draper BS315
- Warco BS312
- Metabo BAS317
Always confirm your bandsaw's blade specifications match before purchase.
Care:
- Keep the blade clean and free from resin or pitch buildup. Use a soft brush or a solvent suitable for metal when needed.
- Store the blade in a dry place to prevent rust. Applying a light coat of oil can offer protection.
- Periodically inspect the teeth for dullness or damage. As the teeth are resharpenable, consider professional sharpening when performance degrades significantly.
