Are broken bandsaw blades a common occurance? I recently bought my first bandsaw and have been feeling very comfortable working around it…much more comfortable than I am around my table saw. Is my sense of security foolish?

I had three Timberwolf blades break…all different sizes , one while cutting 3/4” Pine.
Switched to Olson blades and haven’t had a problem since : )

Dave,

To answer your question; Let me put it this way, I don’t think it’s an uncommon occurance, but It’s not something you should worry about everytime you use your bandsaw. I worked with my bandsaw for years and maybe broke a couple blades in 25 years. I don’t do any resawing with mine, so that type sawing I wouldn’t know if there would be a bigger chance or not.

I read somewhere that people get cut on a bandsaw almost as often as on a table saw. I have a hard time believing that, but then again, I’ve always felt more comfortable getting my fingers closer to the blade on a band saw then on the table saw and they say that’s why people get cut on the bandsaw…........too comfortable making close cuts.

As with any tool, they’re only as safe as the operator. Keep your bandsaw tuned and keep a sharp blade on it and just watch where your fingers are in relationship to the blade when pushing your wood thru. Enjoy.

I have seldom had a blade break. I had some made at a local chop and one did break from a bad weld, but they rewelded it and it should be fine. I used to weld blades and if they are not annealed enough, the weld will be brittle and could break.
Dave, congratulations on getting a band saw. That is one of the most useful tools in my shop.
It is safer than a table saw, but you have to keep the guard down right over the piece and never push with your hand right behind the piece in line with the blade- uses a pusher block.

You need to be aware of how tight a radius you can cut with the blade that you’re using and you have to recognize when the blade is too dull to use. That is when accidents happen because you are pushing too hard.

I’ve had too many eye injuries in my life to do any more work with power tools and no safety glasses. I’ve been lucky so far. I don’t want to push my luck. Safety glasses are always on before the power switch!

Sorry to hear of that unfortunate incident, and hope you didn’t get hurt. Could be a multitude of things that could-have caused it, but, who knows for sure. Just be sure your wheels are co-planer, and all your adjustments are as best as you can get.

Bandsaw blades do break but it should be a rare event. I have broken a 1” and a 1/4” blade but have yet to have one of my Timberwolf blades break.

I have had a couple of blades break over the years. Usually trashes the blade, but it’s also always happened with a blade that was almost shot anyhow. Still not a great thing to do – some risk of injury and also of trashing a wheel tire or some other part of the saw. When they break on a weld, it was probably a poor weld.

I had three bandsaws in my classroom. They got used a lot and we broke two or three every year.

If the blade breaks at the weld, it is usually a sign of poor weld. The usually break in the weld early in their life.

If the blade breaks somewhere else, it is due to a stress crack. Just like bending a wire back and forth will break the wire, the same happens with bandsaw blades. The blade gets bent twice for every revolution as it goes around the wheels. Eventually, the blade will break.

Don’t bother getting a blade re-welded if it broke due to stress. It will soon break somewhere else. A bad weld and be re-welded.

When a blade breaks, it usually makes a LOUD bang and does nothing else. Turn off the saw and wait until the top wheel stops coasting. Don’t open the door early or the blade may jump out at you.

Occasionally, a blade make come out of the saw. Had one break just as it exited the upper wheel cover. Hit me in the back of the hand. Scared the heck out of me but only needed a bandaid. Had one break on a student and just below the table. It shot out of the dust shield across the floor and hit another student running a belt and disc sander about 50 ft. away. Look like a snake slithering across the floor. No harm done other and two frightened kids.

If a blade has been used for a year or more, inspect it for cracks in the gullets of the teeth. When you see a crack, throw it away and change blades.
