Abstract
A hand-held band saw has a handle for grasping the band saw, a motor, a drive wheel driven by the motor, a driven wheel and a continuous blade disposed about the drive wheel and the driven wheel. A portion of the continuous blade is positioned in a cut zone to perform a cutting operation. A workpiece guard is spaced from the continuous blade and positioned generally between the cut zone and the handle for limiting movement of the workpiece after the cutting operation.
Claims27
A hand-held band saw comprising:
- a handle for grasping the band saw;
- a motor;
- a drive wheel driven by the motor;
- a driven wheel;
- a continuous blade disposed about the drive wheel and the driven wheel;
- a cut zone, wherein a portion of the continuous blade is positioned in the cut zone to perform a cutting operation, wherein the cut zone is bounded by first and second planes oriented such that the portion of the continuous blade is substantially normal to the first and second planes;
- and
- a workpiece guard spaced from the continuous blade and positioned generally between the cut zone and the handle for limiting movement of a workpiece after the cutting operation, wherein the workpiece guard is disposed at least partially between the first and second planes.

A hand-held band saw for cutting a workpiece, the hand-held band saw comprising:
- a housing defining a front and a rear, the housing having an opening in the front defining a cut zone and a first housing portion generally located on a first side of the opening and a second housing portion generally located on a second side of the opening;
- a first wheel supported by the first housing portion;
- a second wheel supported by the second housing portion;
- a motor operably coupled to the first wheel;
- a handle disposed proximate the rear of the housing, the handle having a grip portion extending between the first housing portion and the second housing portion;
- a continuous blade supported by the first and second wheels, wherein a portion of the continuous blade is positioned in the cut zone to perform a cutting operation;
- and
- a workpiece guard substantially traversing the cut zone for limiting movement of a workpiece after the cutting operation.
