A method for manufacturing a bandsaw blade provided at the top of the teeth with cutting tips made of a hard material, includes the steps of: offsetting to the left and right saw teeth constituting left and right offset teeth; forming the saw teeth constituting the left and right offset teeth to a smaller tooth height than that of the saw teeth constituting straight teeth; and grinding cutting tips provided to the top of the left and right offset teeth subsequent to the offsetting step, and machining the edge lines at the top of the left and right offset teeth so that the lines are orthogonal to the travel direction of a bandsaw blade and the cutting direction of the bandsaw blade.

Method for manufacturing bandsaw blade, and bandsaw blade

A saw blade,comprises a preceding tooth,constructed by a straight tooth performing no saw setting operation in left-hand and right-hand directions and a succeeding tooth,for cutting a cutting groove formed by the above preceding tooth,to enlarge and open the cutting groove in width. The succeeding tooth,has left-hand and right-hand set teeth,L,,R bent in the left-hand and right-hand directions by splitting an approximately central portion,D of a tooth edge on a tooth line in its thickness direction; and the clearance between end tip insides of the above left-hand and right-hand set teeth,L,,R is smaller than the thickness of the preceding tooth,. Further, the thickness of portions of the left-hand and right-hand set teeth,L,,R near their end tip portions are approximately equal to the thickness of portions of the left-hand and right-hand set teeth near respective base portions thereof.
