A circular saw plunge pipe cutter includes a main housing, a drive mechanism at least partially disposed within the main housing, a saw blade operably coupled with the drive mechanism, and a shoe slidably coupled to the main housing. The shoe includes a pipe receptacle in which a pipe is receivable. The circular saw plunge pipe cutter is adjustable between a plunge state, in which the main housing moves toward the shoe and the saw blade extends into the pipe receptacle, and a retracted state in which the main housing moves away from the shoe and the saw blade does not extend into the pipe receptacle.

A cut member processing device includes a marking device configured to put a mark on a cut surface of a cut member cut out from a metal long workpiece by a cutting device; and a product length acquisition unit configured to measure and store a product length of the cut member. The product length acquisition unit is configured to measure the product length under a state where the cut member is located at a position that allows the marking device to put the mark on the cut surface.

An integrally formed tool arm for a power cutter, the tool arm comprising a first aperture (310) for receiving a motor axle, a second aperture (320) for receiving a tool axle of a rotatable work tool, wherein the first aperture (310) and the second aperture (320) are intersected by and orthogonal to a longitudinal extension axis of the tool arm, the tool arm further comprising first rail cutting accessory attachment means (330) arranged to receive a rail cutting accessory, wherein the first rail cutting accessory attachment means (330) is arranged offset from the longitudinal extension axis of the power cutter arm.

An electric working machine may include an output shaft, a rotary blade attached to the output shaft, an output pulley fixed to the output shaft, an input shaft, an input pulley fixed to the input shaft, a transmission belt wrapped around the input pulley and the output pulley, an electric motor including a motor shaft and configured to rotate the motor shaft, a speed reducer configured to reduce a speed of rotation of the motor shaft and transmit the rotation to the input shaft, and a housing that houses the electric motor and the speed reducer, and rotatably supports the input shaft and the output shaft. A rotation axis of the motor shaft may be inclined with respect to a direction which is along a rotation axis of the output shaft.

A compact, portable device is attachable to an impact driver or drill motor to cut electrical cable metal cladding without damage to conductors thereunder when used properly. The device comprises a cross member, a housing, an intermediary component held under tension in the housing, and a small saw blade. An electrical cable may be held in an intermediary component cable channel by a pair of spring pins extending downwardly from the cross member into the channel in response to downward manual pressure to the cross member by a user. The intermediary component and the housing are configured to permit vertical sliding movement of the saw blade in response to application of upward manual pressure to the housing by a user. As the bottom of the tool is compressed manually, a portion of the saw blade is permitted to enter the channel through a channel bottom slit to cut the cladding.

A rail adapter may include a mount configured to couple to the workpiece. A rail adapter may include a first arm having a first end pivotably coupled to the mount about a first pivot axis and an opposite second end. A rail adapter may include a second arm having a first end pivotably coupled to the first arm about a second pivot axis and an opposite second end. A rail adapter may include a mounting bracket pivotably coupled to the second end of the second arm and mounted to the saw. A rail adapter may include a first pivot lock engageable to inhibit a first degree of freedom of the mounting bracket and the saw. A rail adapter may include a second pivot lock engageable to inhibit a second degree of freedom of the mounting bracket and the saw, the second degree of freedom being different from the first.
