A flute extends generally along with the tool's axis and defines a straight cutting edge and contour cutting edge. The system may include a fixture with vacuum cups nested within a platform so as to secure a contoured workpiece by static friction, permitting edges of the workpiece to be both trimmed and smoothly finished using a multi-purpose edge finishing tool, without marring or disfiguring the surface of the workpiece.

Abstract: A drill powered reciprocating saw including a safety gear assembly which disengages the saw's drive mechanism should the operator lose his or her grip on the saw housing. The gear assembly includes a motor drive shaft that is connected to an electric drill and which drives a jackshaft by means of a pair of interlocking gears. At rest, the drive shaft is biased by a spring to a position where the gears are not in contact with each other. When the operator pulls the saw housing toward the drill, the spring is compressed and the gears are engaged, thus allowing the saw to operate. Should the operator lose his or her grip on the housing, the spring biases the drive shaft back to its original position, thereby disengaging the gears.

Abstract: The invention disclosed herein is a simple but versatile sawing device for effectively and efficiently cutting or sawing hard solid materials. A driving mechanism consisting of three slidably-associated elements converts a rotational force into a dual rotatory/reciprocatory motion. A cam key may be disengaged to permit the device to be used to drill into a surface. Also disclosed is a novel cutting-rod element that is a hard metal rod with cutting teeth of a unique shape on its surface.

Abstract: A flat drill bit having a shaft with an axis of rotation and a flat drill bit head connected to the shaft. The flat drill bit head includes opposing flat front and back faces, left and right edgewalls between the front and back faces, and a bottom endwall connected to the left and right edgewalls. The left and right edgewalls are angled relative to the front and back faces so as to define left and right cutting edges that are parallel to the axis of rotation. The bottom endwall includes left and right sections, each being angled in opposite directions relative to the front and back faces so as to define left and right bottom cutting edges. The bottom endwall of the drill bit head has a rounded shape thereby providing curved left and right bottom cutting edges. In an alternate embodiment the bottom endwall is generally straight, thereby providing straight left and right bottom cutting edges.
