A portable band saw device including a frame supporting a prime mover which drives a first pulley, a second pulley being supported on an arm pivotally connected to the frame so that said second pulley is movable relatively toward and away from the driven pulley against the resistance of a spring, the band saw blade being extended around the two pulleys and guided by arrangements on one side of the frame, while a guard on the opposite side prevents inadvertent cutting at that location, both pulleys having provisions for adjustments of their axes of rotation, including an arrangement for tilting the arm carrying the second pulley.
