Bandsaw Blade Life

[TimD]

Hi

A few months ago I put a TuffSaw 5/8" blade in a Record Power BS300.
It has been used as a hobby machine, perhaps one whorkshop session a fortnight for about 5 months. The performance has been fine, but a couple of days a ago, the blade snapped. I wasn't even cutting at the time, it was free running.

Is a snapping blade a sign of gereral wear & tear, and to be expected, or is this a case of taking it up with TuffSaws.

I am a new to owning a Bandsaw, however I spent a lot of time setting up, and believe the tensioning was correct.

Any advice?


Thanks

Tim

Where did the break occur, at the weld, at the tooth root/bottom of the gullet?
If at the root are there any signs of cracks starting in other places.
Was there any sign/sound of blade vibrating before the break?

Hi CHJ

There was no vibration / noise.
The break appears to be at the wled, no visible cracking.

Attached photo to show break.

Thanks

Sounds like work hardening/failing/defect propagation of/in the weld, have a word with Ian.

CHJ - Thanks for the comments.
Will have a chat with TuffSaws.

I've had one of Ian's blades go at the weld - he replaced with no quibble in the next post. Top bloke.

Lots of talk of snapped blades from Tuffsaws on here as well as how well they cut. Conclusion is they use a hard steel which takes a good edge but not as flexible as some. There is always a compromise to make.
