Provided is a work machine with improved operatability. In a cutting tool, a guard member that is made of metal is provided inside a chip discharge passage section, and a bottom wall of the chip discharge passage section on a saw blade side is covered by the guard member. In other words, a bottom surface of the chip discharge passage section is guarded by the guard member that is made of metal. Accordingly, the guard member can prevent high-temperature metal chips from coming into direct contact with the bottom wall of the chip discharge passage section. Thus, deformation of the chip discharge passage section when chips pass through the chip discharge passage section can be suppressed. Consequently, the durability of a saw cover can be increased, and the operatability of the cutting tool can be improved.

A jigsaw that includes a housing assembly, a shoe member and an indicator. The housing assembly has a housing, a motor and transmission assembly received in the housing, an output member reciprocatingly driven by the motor and transmission assembly, and a trigger coupled to the housing and configured to control operation of the motor and transmission assembly. The housing defines a window. The shoe member is pivotally coupled to the housing. The indicator is pivotally disposed in the housing. A portion of the indicator is visible through the window. Movement of the indicator is responsive to movement of the shoe member such that a rotational position of the indicator is indicative of a position of the shoe member relative to the housing assembly.

A modular blast gate for a dust collection system. The blast gate includes first and second regions. The first region has a first configuration and enables securement of a duct of the dust collection system to the first region via a first connector mechanism. The second region has a second configuration different from the first configuration and enables securement of the duct to the second region via a second connector mechanism different from the first connector mechanism. The blast gate is usable to connect differently configured ducts, hoses, or pipes to equipment that generates particulate material. The blast gate is mountable to the equipment or a support surface. Two of the modular blast gates may be joined to one another to enable two ducts to be connected together.

A power tool arrangement includes a frame having an outlet. A power tool is coupled to the frame and includes a movable working element configured to engage a work piece. A hose includes first and second opposite ends and a biasing device configured to bias the hose into a longitudinally compressed position. The first end is coupled to the outlet. The second end is coupled to the working element such that the second end follows the movement of the working element and the hose thereby moves between the longitudinally compressed position and a longitudinally expanded position.

A dust case has improved operability for attachment and detachment. A portable cutting machine includes a cutting machine body to which a blade being circular is attachable, and a dust case detachably attached to the cutting machine body. The dust case includes a detachment operation unit pushable along an imaginary plane parallel to a surface of the blade in detachment from the cutting machine body, and a finger support including a surface frontward from the detachment operation unit in a pushing direction in which the detachment operation unit is pushed. The surface is substantially perpendicular to the pushing direction.

A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

A band saw machine is adapted for cutting a lumber, and includes a frame body unit, a transport unit, a cutting unit, a cleaning unit and a guide unit. The frame body unit includes a base plate and a hood body extending rearward from the base plate and cooperating with a conveyor belt of the transport unit to define an output passage. The cutting unit is adapted to cut the lumber into an upper piece and a lower piece. The guide unit includes two guide rollers mounted to the hood body, extending into the outlet passage, and adapted to separate the upper piece from the lower piece. The cleaning unit includes an air lance for directing an air stream to the conveyor belt.

A blade clamp with first and second gripping members configured to hold a cutting blade, a lever connected to the clamp by a connection member, and a head that receives the connection member that extends through an aperture of the head. The connection member can move along a first axis through the aperture of the head and move the clamp along the first axis based on a position of the lever. The first and the second gripping members of the clamp can clamp the cutting blade along a second axis orthogonal to the first axis based on a position of the clamp along the first axis. The lever can include an eccentric cam surface that engages a cam follower. The eccentric cam surface can cause the clamp to provide a clamping force and tension to the cutting blade.

A hand-held power tool includes an SDS tool receiver and a tool housing. The SDS tool receiver includes at least one vacuuming-off channel and is configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece. The tool housing includes at least one drive unit configured to drive the exchangeable insert tool.

A Dust Capturing Device for Reciprocating Saws is disclosed. The device is attachable to a convenational shop vacuum cleaner so that virtually all dust created by the reciprocating saw at the cutting blade is captured by the vacuum cleaner. The system is universally attachable to all powered reciprocating saws on the market. A pair of suction hoses are snugly attached to the body of the saw, from intake ports located adjacent to the saw blade to an adapter manifold that combines the two suction hoses into a single hose adaptable to the vacuum cleaner hose. The hoses are attached to the body of the saw by one or more body straps, with each body strap having a pair of hose clips extending therefrom for restraining the two suction hoses running along the body.
