Hey guys,

it's been a few years since I installed a new bandsaw blade on my saw. It takes 133" long blades and currently and since the beginning i have been using Lenox Diemaster 2 blades which are 3/8" wide and have a 10/14 vari tooth.

So I installed one probably an hour ago and had it running at the usual 150FPM and started to cut the usual 1/8" thickness A2 stock. I noticed I was kinda getting hit by fragments (which I realized were the teeth shearing off!!)

Is that too fast to break a blade in with? Should I be cutting 1/8" stock with a blade that has more TPI ?

It's kinda annoying to have teeth breaking off about 2 minutes into cutting!

Should I have broken in the blade cutting thicker stock like 1/4" or was it simply a factor of me pushing the metal in too fast to the blade?

Thanks in advance as usual!

Pohan
 
I do cuts like that with the material laying flat, not edge up.

right! The material is laying flat. How odd!

the odd part is that prior bandsaw blades did not have this problem!

and there are teeth popping off?

eh...

...hum

...I don't know what the problem would be. 150 SFM is about twice what I would run, but the problem would be premature dulling, not teeth popping off. Is it a big hook tooth like you'd use on wood or plastic?

No it's not. It's definitely a diemaster 2 blade for metal. The odd part also is that little sections of teeth have sheared off and others remain in tact. maybe i'm running it too slow!

The Lenox Advantage
M-42 high speed tooth edge
For durability.
Designed to run at high speed
Runs at twice the speed of carbon.
Increased blade life
Lasts 10 times longer than carbon blades.
General purpose hand-fed applications
Tool and die shops, machine shops, maintenance facilities.

is what I found on a website....
 
If i was cutting right at the edge of a piece of steel and the steel
wasn't laying completely FLAT on the bandsaw table and the blade
somehow caused the piece of metal to be pushed even a little off the
table where it was sitting at an angle, could this cause tooth breakage?
