A saw machine worktable positioning mechanism includes a pivot shaft, an operating member and a first positioning unit so arranged that operating the operating member can drive the first positioning unit to move a positioning member of the first positioning unit relative to the base of the saw machine in one of two reversed directions to lock the worktable of the saw machine to the base or to unlock the worktable from the base.

A power tool is provided including a tool housing; at least one battery receptacle accommodated on the tool housing, the battery receptacle being adapted to receive a battery pack having a maximum voltage of at least 60 volts; and a brushless DC (BLDC) motor disposed within the tool housing, the motor including a stator assembly and a rotor assembly rotatably disposed within the stator assembly. A motor control and power module is disposed in close proximity to the motor, including a power switch circuit electrically coupled to the motor and a first controller configured to control a switching operation of the power switch circuit for supply of power from the battery pack to the motor. A battery management control module is disposed in close proximity to the battery receptacle, including a second controller distinct from the first controller, the second controller configured to manage an operation of the battery pack.

A tile saw includes a base, a frame assembly disposed on the base, a first rail disposed on the frame assembly, the first rail having a longitudinal axis, a table slidingly disposed on the first rail, a support assembly disposed on the base, a saw assembly supported by the support assembly, the saw assembly having a motor, a cutting wheel driven by the motor, the saw assembly being pivotable about a horizontal axis substantially parallel to the longitudinal axis, and a switch electrically connected to the motor and disposed on the support assembly so that, when the motor assembly is pivoted about the horizontal axis, the switch remains stationary.

A miter saw includes a base, a turntable, a support assembly, and a cutting arm. The turntable is rotatably connected to the base, and the support assembly fixedly extends from the turntable. The cutting arm is pivotally connected to the support assembly. The miter saw further includes an arbor assembly, a gear assembly, a first belt member, and a second belt member. The arbor assembly is rotatably supported by the cutting arm. The gear assembly is supported by the cutting arm and positioned outside of a nominal blade space of the miter saw. The first belt member is operatively connected to the arbor assembly and the gear assembly. The second belt member is operatively connected to the gear assembly and to a motor shaft.

A cutting machine may include a table configured to place thereon a workpiece to be cut, a cutting unit having a cutter and tiltable relative to the table, and a position determining mechanism operable for determining a position of the cutting unit at a plurality of set positions including a vertical position and a plurality of tilt positions where the cutting unit is tilted from the vertical direction. The position determining mechanism may include an operation member operable by a user, and a switching device couple to the operation member and configured to switch the position of the cutting unit to be determined between the plurality of set positions according to the operation of the operation member.

A sawing device, in particular a circular saw bench or crosscut saw, including a workpiece support for supporting a workpiece, a saw blade, and an electrical actuator device for setting a saw blade position of the saw blade relative to the workpiece support. The electrical actuator device has a first electrical actuator which includes a first rotor and serves to set the saw blade position in a first degree of freedom, in particular a saw blade angle, and the sawing device is designed to detect a current saw blade position of the saw blade on the basis of a first rotor movement of the first rotor.

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.

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 circular saw including a base defining a longitudinal axis. The circular saw further includes a front bevel angle adjustment bracket proximate a front end of the base and a rear bevel angle adjustment bracket proximate a rear end of the base. The circular saw further includes a saw unit coupled to the base via the front bevel angle adjustment bracket and the rear bevel angle adjustment bracket. The circular saw further comprises a first fastener extending through a first elongated slot in one of the base or the front bevel angle adjustment bracket and a second fastener extending through a second elongated slot in one of the base or the rear bevel angle adjustment bracket. Each of the first and second elongated slots extends along a lateral axis oriented transverse to the longitudinal axis of the base to permit lateral adjustment of the saw unit relative to the base.
