A saw guide for a saw arbor guide assembly comprises a head, a body, a pad, and one or more temperatures sensors. The saw guide comprises one or more sensor channels extending between first and second faces thereof. The pad extends across at least one of the first and second faces, and the pad comprises one or more pad channels. The pad faces a corresponding saw blade. Each of the temperature sensors is located within one of the sensor channels. In addition, each of the temperature sensors comprises a sensor body, a tip, and a thermocouple. The tip extends from the sensor body and is adapted to extend, at least partially, through one of the pad channels and be spaced apart from the corresponding saw blade. The thermocouple is enclosed within the tip, with the thermocouple configured to measure changes in temperature of the corresponding saw blade.

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 itself including 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. 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.

A machining device may include an electric motor, a blade rotatably driven by the electric motor for machining a workpiece, and a blade cover configured to surround the blade. A resonance sound reduction device may be disposed at the blade cover and may reduce air vibration generated by the rotation of the blade.

Cutting protection guide for cutting tools. The Cutting protection guide includes different clamping components providing plural adjustable clamping pressures at plural different vertical and horizontal and arc curve position locations for a clamping point to clamp down and securely hold a piece of material being cut on a cutting saw. The cutting protection guide allows very small pieces (e.g., about 1 to 2 inches or less, etc.) of materials (e.g., wood, metal, plastic, etc.) to be safely cut without endangering a safety of a user using the cutting saw.

A handheld work apparatus includes a housing and a work tool arranged on the front end. The housing has a back end to which an operator region is assigned. The housing has a first and a second shell separable in a separation direction. The operator region, in the region of the back end, is bounded by a tubular section of an outer housing wall. The outer wall of the first shell is reinforced in the region of the tubular section by a rib structure inside the housing. In a view in the separation direction of the inner side of the first shell, in the region of the tubular section, the first shell has an interconnected rigid rib region and an interconnected elastic expansion region. The expansion region is directly adjacent to the rib region and is at a greater distance from the back end than the rib region.

A handheld work apparatus includes a housing (2). A drive motor (3) is arranged in the housing (2) for driving a tool (2) that rotates about an axis of rotation (8). A protective hood (51) at least partially covers the tool (5). An operating stop (120) is fixed relative to the housing (2) and a counter-body (110) is arranged on the protective hood (51) and corresponds to the operating stop (120). The operating stop (120) is designed as an energy absorption element which, in the event of an excess load acting on the operating stop (120) due to the counter-body (110), moves away from the counter-body (110) in order to absorb kinetic energy of the protective hood (51) and to protect components of the counter-body (110). The work apparatus (1) includes an end stop (101) for restricting the rotational movement of the protective hood (51) to an end position (25).

A support pad for a saw guide includes a first pad face and a second pad face opposite the first pad face. The first pad face includes an inner region and an outer region. The outer region surrounds the inner region. The outer region includes at least two pad openings and a pad channel. The pad openings are adapted to allow lubricant from the saw guide to pass through the support pad and to exit from the outer region. The pad channel extends between at least two of the pad openings. The pad channel provides a path for the lubricant to travel. The second pad face is adapted to be attached to the saw guide.
