A reciprocating cutter system for use in spaces where a typical saw is unable to operate due to size, space, and operability limitations is disclosed. In at least one embodiment a reciprocating cutter system includes: a housing; a handle disposed on a top portion of the housing to provide an operator a user grip to operate the system; a cable saw coupled to the housing of reciprocating cutter system; a spring disposed within the housing and coupled to the cable saw such that as the cable saw is moved in a back-and-forth motion when in use, the spring also moves in a back-and forth-motion without the operator-held handle needing to move; and a connectivity bit, coupled to the cable saw, to connect the wire saw through the connectivity bit to a reciprocating device, the reciprocating device to provide the back-and-forth motion to the connectivity bit and the cable saw.

ELECTRIC CUTTING SYSTEM

An electric power saw/cutter includes a rotatable saw structure, a rear handle with a switch/speed control, a front handle, and a drive unit for rotating the saw structure. The drive unit includes a saw structure drive arrangement to which the saw structure is attachable, a transmission for driving the saw drive arrangement, an electric motor for driving an input shaft of the transmission, and a support structure for holding/carrying the saw structure drive arrangement. The transmission and the electric motor may be characterized in that the front handle and the rear handle are directly connected to each other to form a handle unit, which unit is resiliently connected to the drive unit, so that vibrations from the saw blade and drive unit will be reduced in the handle unit.

The present invention relates to a reciprocating wire saw device. The device is primarily comprised of a body with at least one handle, at least one trigger, at least one battery, and a second end with at least one blade and at least one plunger. The device preferably has two oscillating arms that oscillate independently via the motor. Therefore, each end of a wire blade can be attached to each arm such that oscillation of the arms allow the blade to cut a pipe or other similar object.

A rotatable multi-tool power saw apparatus may comprise a rotatable cutting head with a base plate. A rotating plate assembly may be rotatably mounted to the base plate and may be configured to position a cutting blade or other tools at multiple angular orientations. Left and right extension arms may extend from the base plate. A cutting blade may receive motive force from a motorized tool and rotate about the cutting head to contact a workpiece. A tool clamp mechanism may mount to the rotatable cutting head and may include a hinged clamp to secure the cutting head to the motorized tool. One or more handles may mount to the apparatus for user control.
