Frequently Asked Questions
Which bandsaw is it compatible with?
It is specific for industrial metal bandsaws (blade stroke 4130 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 the 4-6 TPI toothing used for?
Suitable for cutting large sections and solid profiles (>50 mm), mild steels, and non-ferrous alloys. VARIO pitch (variable pitch teeth) reduces vibrations and extends service life compared to fixed pitch.
General rule for metal: low TPI (4-6) for large solids, 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 34 mm width?
It is suitable for industrial straight cuts with maximum rigidity (no curves).
The width determines rigidity and the type of cut possible. For metals, a bimetallic blade (Biflex) with M42 HSS steel teeth brazed onto a flexible body is always required.
What does Biflex mean?
Biflex is a bimetallic blade with a flexible steel body and M42 HSS steel teeth, optimized for metal cutting.
M42 teeth (HSS-Co8 with a high percentage of cobalt) resist temperatures up to 600 °C and maintain sharpness on hardened steels and hard alloys. The bimetallic structure combines the flexibility of the body and the hardness of the teeth.
How to tension it correctly?
Typical tension for metal blades: 25,000-35,000 PSI. Incorrect tension is the primary 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 stress. Always consult the saw's manual for the exact value. Check cold after 5 minutes of operation.
