A sheet material cutter and bending brake combination includes a sheet bending brake having a base member with a clamp surface, and an anvil member for clamping sheet material against the clamp surface. The anvil member has a track extending longitudinally of the anvil member and the brake. The track includes a pair of parallel channels that are at an angle to each other, and are laterally spaced from each other-i.e., laterally of the longitudinal dimension of the brake and the longitudinal direction of the track. The track also includes a second channel extending along the anvil member parallel to the first channel and disposed between the lip and the clamp surface. A cutter has a frame, and first and second pairs of track rollers mounted on the frame. The first pair of track rollers have outwardly extending peripheries for receipt in the first channel, and the second pair of track rollers have outwardly extending peripheries for receipt in the second channel. A pair of cutter rollers on the frame are disposed for engagement with sheet material clamped between the anvil and base members when the cutter is mounted on the track. The track and track roller geometries provide affirmative wheel locking in the track, which reduces any tendency of the cutter to become untracked as the cutter is propelled along the sheet bending brake.
