A portable machining apparatus includes a main body, a cover including a cover main body and a door, a door open/close mechanism, and a lock to lock the open/close mechanism in a closed state displaceably supported by the cover main body or the main body portion. The main body is displaceable relative to the cover between a first position entirely containing the tip tool in the cover, and a second position partially exposing the tip tool outside the cover. The lock is manually displaceable between a position blocking the door from opening, and a position permitting the door to open. The lock is displaceable when the main body is at the first position, and is not displaceable by abutment between the other of the cover main body and the main body and the lock operation member when the main body is at a position other than the first position.

Portable machining apparatus

The dust proof circular saw has a main body with a rotating disc cutter blade and a cover fixed to the body to cover a blade outer radial periphery part. The body is supported by a base such that an angle of the body in the up-down and right-left directions can be adjusted at a base upper side. A further blade outer radial periphery is covered by an auxiliary cover. The auxiliary cover covers a gap between the fixed cover and the base. The auxiliary cover is moved by a mechanism relative to the body in accordance with an angle of the circular saw main body relative to the base in the up-down direction. The auxiliary cover is pivotally connected to the base, and is pivoted around a laterally tilting support shaft in the right-left direction by an interlock mechanism in accordance with a body angle in the right-left direction.

Portable cutting devices

A communication adapterfor conducting radio communication between a portable machining deviceand a dust collector, such that the dust collectormay operate synchronously with the portable machining devicewith respect to a start/stop operation when performing a cutting task is detachably incorporated in a handleof the portable machining device. Because of this arrangement, a high level of dust-proof ability as well as ease of maneuverability in attaching and detaching the communication adaptercan be achieved.

Portable machining device

An electric tool may include a tubular housing, a motor disposed within the housing, and a tool holder rotatably driven by the motor and capable of holding an end tool. A shoe may be supported by the housing and may determine a protruding length of the end tool from one end of the housing. A battery mount portion may be disposed at the other end of the housing. The battery may be mounted to the battery mount portion as the battery is slid relative to the battery mount portion along a direction intersecting the extending direction of the housing.

Electric tools

Electric tool having housing, tool holder, shoe and battery mounting portion which slidably receives battery

A shoe attached to a shoe attachment portion includes a spanner portion. As the shoe can be separated from a tool main body of the cutout tool, the shoe can be used as a spanner. The shoe can function as the spanner for replacing a bit in a bit attachment mechanism. In addition, the shoe has its original function of the shoe by which a protrusion amount of the bit can be adjusted. Since the shoe is attached to the shoe attachment portion and held by the tool main body, it turns out that the spanner can be prepared for use with the cutout tool.

Electric power tool

A cutting device may include a cutting unit having a cutter for trimming an edge portion of a workpiece or forming a groove in a workpiece. The cutting device may further include a base assembly configured to support the cutting unit with respect to the workpiece, and a grip device capable of being mounted to and removed from the cutting unit independently of the base assembly and configured to be capable of being grasped by a user during a cutting operation.
