    摘要: A method for producing a saw blade having saw teeth arranged along a tooth side includes connecting carbide teeth to a tooth support by introducing heat and removing material from the saw blade tip until a distance between the tooth face of the front saw tooth and the saw blade tip does not exceed a limit value.

    摘要: A powered coping saw has a frame that includes a first leg, a second leg and a third leg. A blade is reciprocally movable in a first and second direction with respect to the frame. First and second blade mounting brackets are provided for mounting the respective first and second ends of the blade. A blade driver is coupled to both the first and the second blade mounting brackets for actively driving both the first and the second ends of the blade in both the first and the second directions. The blade driver includes a motor, a transmission, a first drive member, and a first pivoting arm member. The first pivoting arm member has a first end pivotally coupled to the first drive member, and a second end. A reciprocally moving arm member has a first end pivotally coupled to the second end of the first pivoting arm member, and a second end. A second pivoting arm member has a first end pivotally coupled to the second end of the reciprocally moving arm member, and a second end. A second drive member is pivotally coupled to the second end of the second pivoting arm, and is coupled to the second blade mounting bracket for actively, reciprocally driving the second blade mounting bracket (and hence the blade) in both the first and second directions.
