Frequently Asked Questions
Which bandsaw is it compatible with?
It is specific for professional Bernardo MSB series metal bandsaws (blade stroke 3970 mm).
Check the blade stroke (closed blade length) of your saw before purchasing. The length is indicated in the machine manual or printed on the existing blade.
What is 12 TPI tooth pitch used for?
Suitable for cutting thin tubes and sheets (10-20 mm), a good compromise between speed and finish.
General rule for metal: low TPI (4-6) for large solid materials, medium TPI (8-10) for tubular profiles, high TPI (12-14) for thin sheets and thin-walled tubes. Typical cutting speed: 30-90 m/min on mild steel.
What can be cut with a 6 mm width?
It is suitable for contour cutting and curves, blades for small bench saws.
The width determines rigidity and the type of cut possible. For metals, a bimetallic blade (Biflex) with M42 HSS teeth on a flexible body is always needed.
What does Biflex mean?
Biflex is a bimetallic blade with a flexible steel body and HSS M42 steel teeth, optimized for metal cutting.
M42 teeth (HSS-Co8 with a high cobalt percentage) resist temperatures up to 600 °C and maintain sharpness on hardened steels and hard alloys. The bimetallic structure combines body flexibility and teeth hardness.
How to tension it correctly?
Typical tension for metal blades: 25,000-35,000 PSI. Incorrect tension is the main cause of premature breakage.
Blades that are too loose cut crooked and break due to fatigue; blades that are too tight break due to mechanical tension. Always consult the saw manual for the exact value. Check cold after 5 minutes of operation.
