A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.

Systems and methods are provided for an electric tool (e.g., a power tool) that includes an output driver for receiving an accessory, and an accessory-type detector. A motor of the electric tool is coupled to the output driver for driving the accessory. The power tool also includes an operation trigger for activating the motor and a motor controller. The motor controller includes an electronic processor that is coupled to the accessory-type detector, the motor, the operation trigger, and a memory. The memory stores instructions that when executed by the electronic processor cause the motor controller to detect a characteristic of the accessory from output of the accessory-type detector. The motor controller determines an operational characteristic for the accessory based on the detected characteristic, and controls operation of the motor to drive the accessory according to the operational characteristic when the operation trigger is activated.

A cutting machine reduces cost increase associated with production equipment and has design flexibility for different types of batteries. A cutting machine for cutting a workpiece includes a cutting machine body including a cutting blade, a motor that drives the cutting blade, and a motor housing accommodating the motor, and an adapter including a body holder attached to the cutting machine body and a battery holder in which a battery to power the motor is installable.

An improved chop saw cutting deck is moveably attached to a chop saw base with a hinge mechanism. The axis of the hinge mechanism is perpendicular to the vertical axis of the chop saw's cutting wheel, thereby allowing a change to the angle of inclination between the cutting wheel and materials placed on the cutting deck. For certain material profiles, this alternate inclination angle presents a smaller material surface area to the cutting wheel, and translates to cooler, faster, and more efficient abrasive cutting action. The cutting deck is supported in its inclined position by a deck support means, and may be reconfigured back to a horizontal orientation for effective cutting of various other material profiles. In addition, the preferred location of the hinge axis provides a consistent, lateral line of elevation across the cutting deck, thereby assuring continuous contact of elongated materials with supplemental material supports, such as sawhorses, throughout the cutting deck's range of motion.

A shaft cutting tool incorporating a scissor assembly having a first arm, a second arm, and a hinge interconnecting the arms' proximal ends; a shaft mount attached to the first arm's distal end; and a cutting wheel assembly operatively mounted within a hollow bore formed at the second arm's distal end; wherein the cutting wheel assembly includes a drive axle and rotary bearing; and wherein the drive axle extends oppositely from the cutting wheel for engagement with a portable electric drill.

A miter saw that includes a base, a worktable arranged on the base and defining a worktable plane, and a cutting head formed with or connected to an operating member operable by a user. The cutting head further includes a circular saw blade operative to rotate around a first axis and a motor operative to drive the circular saw blade. A fence is arranged on the worktable. The cutting head is further connected to a first guiding member configured for guiding chips to be discharged. The fence is formed with a guiding portion. The cutting head is operative to rotate around a second axis parallel to the worktable plane and, when the cutting head rotates around the second axis, the guiding portion is operative to guide the first guiding member to cross the fence.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a motor for driving a saw blade about a rotational axis, a handle, a trigger coupled to the handle and moveable between a first position in which the motor is deactivated, and a second position in which the motor is activated to drive the saw blade, and a trigger lock pivotably coupled to the trigger for movement therewith to prevent movement of the trigger from the first position to the second position.

A wet cutting saw for cutting a ground portion, the wet cutting saw including a blade rotatable about an axis, a liquid feed conduit for feeding liquid onto a surface of the blade as it rotates, a frame for carrying the blade and configured to travel over a surface of the ground portion, and a mounting assembly that mounts the blade to the frame, at least part of the mounting assembly pivotable relative to the frame to raise and lower the blade relative to the frame.

A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.
