Repair broken band saw blades with the push of a button to get back to cutting without purchasing a new blade. You can also join the ends of coil stock to make custom-sized blades. These all-in-one welders are so straightforward to operate, they’re often found in high school shop classes.

No matter what angle your blade breaks at, the cutting tool slices like a paper cutter to make straight edges that are ready to weld. Adjustable clamps grip the body of your blade to keep welds aligned and prevent the cutting teeth from distorting. After welding, heat-treat the blade with a few taps of the button until the metal is cherry red to strengthen the joint and minimize future breaks. These welders have a holder on top that keeps the blade steady as you use a coarse grit file (not included) to remove any welding residue that could snag in your saw.
