Portable band saw
A portable band saw reduces the overall size increase when a larger controller is included. A portable band saw includes a first saw wheel, a second saw wheel, a band saw blade placed on the first and second saw wheels, a motor that drives the first saw wheel and has a rotation axis in a front-rear direction, a controller that controls the motor, and a housing including a first housing accommodating the first saw wheel, a second housing accommodating the second saw wheel, and a bridge housing accommodating the motor between the first and second housings. The band saw blade is at least partly in an opening below the bridge housing. The controller is in the bridge housing with its maximum surface facing upward.
COPING SAW
The present invention is a coping saw for performing a coping operation. The saw is operable in a first orientation for performing a first cut and in a second orientation for performing a coping second cut and comprises a handle having one or more power switches for activating and deactivating the drive system in both the first orientation and in the second orientation.

Coping saw
The present invention is a new and improved coping saw for performing a coping operation. The saw is operable in a first orientation for performing a first cut and in a second orientation for performing a coping second cut and comprises a handle having one or more power switches for activating and deactivating the drive system in both the first orientation and in the second orientation.
BAND SAW
A handheld band saw includes a saw blade, a housing having a deck surrounding the saw blade, and a handle coupled to the housing and configured to be grasped by a user during a cutting operation. The deck includes a mounting hub extending from the deck. A motor is supported by the housing for driving a drive wheel spindle. The handheld band saw further includes a drive wheel assembly including a drive wheel driven by the drive wheel spindle and a driven wheel driven by the drive wheel via the saw blade. A bearing supports the drive wheel for rotation on the mounting hub. The mounting hub includes an aperture through which the drive wheel spindle extends.

BAND SAW
A band saw including a housing defining a longitudinal axis, a motor, a battery pack removably coupled to a central portion of the housing, a drive wheel assembly positioned within a deck portion of the housing, an opening defined within the deck portion, an endless saw blade, and a rear handle having a curvilinear shape with a first handle end coupled to the central portion and a second handle end adjacent to the deck portion. The rear handle defines a curved path extending between a first end point at the first handle end and a second end point at the second handle end. A first tangent line is tangent to the curved path at the first end point and extends parallel to the longitudinal axis. A second tangent line is tangent to the curved path at the second end point and extends perpendicular to the longitudinal axis.

Band saw
A band saw including a housing, a motor, a drive pulley configured to receive torque from the motor, and a plurality of driven pulleys rotatably coupled to a plate, in which the plate is coupled to the housing for sliding movement. The band saw further includes a cavity within the housing and located between the drive pulley and the plurality of driven pulleys and an endless saw blade wrapped around the drive pulley and the plurality of driven pulleys. A first of the driven pulleys is rotatable about a first axis oriented perpendicular to the plate. A second of the driven pulleys is rotatable about a second axis that is obliquely oriented relative to the plate to impart a twisting movement to the saw blade about an oblong path defined by the saw blade, prior to the saw blade passing through the cavity.
