TimberWolf H8681 124" x 1/2" x .025" x 10 TPI Raker Bandsaw Blade

Comment: I've had 4 of these blades in the 137" length in various widths/teeth. Of those, 3 had the ends welded crooked. If you hold the back of the blade against a flat surface, you can see a 1/8"-1/16" dip or bulge around the weld. When I run these on my bandsaw (Jet 18") every revolution they go 'whump! whump! whump!' as they hit the rear carter bearing. The wood also jumps on each revolution, making it impossible to cut a straight line.

Of the three brands of saw blades I've used, these are the only ones with this problem.

I tried filing/honing the bump off of one blade and simply gave up after 90 minutes. The other two I'm returning.

This might be a phenomena with the longer blades; I haven't tried any of the shorter blades.

The one that did have a flat back worked like a dream - smooth cuts, long lasting, quiet - everything the manufacturer claimed and then some. If they can ever get the weld figured out, I'll go back to them, but for now, I'll spend my money on something that doesn't last as long, but at least doesn't beat my saw to death.
