A power tool adapted to impart axial impacts to a tool bit includes a housing having a motor housing portion and a handle portion extending transversely from the motor housing portion, an electric motor supported in the motor housing portion and defining a motor axis, a non-rotatable barrel extending from the motor housing portion and defining a barrel axis parallel to the motor axis, a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston received within the barrel for reciprocation therein along the barrel axis, a striker received within the barrel for reciprocation in response to the reciprocation of the piston, and an anvil at least partially received within the barrel and positioned between the striker and tool bit. The anvil communicates axial impacts to the tool bit in response to reciprocation of the striker.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and a lower blade guard covering a lower portion of the saw blade. The miter saw also includes a linkage for raising the lower blade guard to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly. The linkage is operable to apply a force to the lower blade guard for holding the lower blade guard in a raised position, without any input from the operator of the miter saw and without changing the length of the linkage, to facilitate changing the saw blade.

The present disclosure is directed to a power tool adapted to impart axial impacts to a tool bit. The power tool includes a housing, an electric motor, and a barrel. The power tool also includes a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston that is received within the barrel for reciprocation therein. The power tool further includes a striker received within the barrel for reciprocation in response to reciprocation of the piston, and an anvil received within the barrel between the striker and the tool bit. The anvil is configured to communicate axial impacts to the tool bit in response to reciprocation of the striker. The anvil defines an opening and an inner bore that communicates with the opening, and the inner bore at least partially receives a shank of the tool bit.

An impact power tool including a housing, a motor supported by the housing, a spindle coupled to the motor for receiving torque from the motor to cause the spindle to rotate, and a reciprocating impact mechanism operable to create a variable pressure air spring within the spindle. The impact mechanism includes a striker received within the spindle that reciprocates along a reciprocation axis in response to the variable pressure air spring, a piston that reciprocates along the reciprocation axis to induce the variable pressure air spring, and a crankshaft configured to convert continuous rotational motion from the motor to reciprocating linear movement of the piston. The crankshaft defines a crank axis perpendicular to the reciprocation axis, and the motor defines a motor axis that is parallel with the reciprocation axis. A center of gravity of the impact power tool is positioned between the motor axis and the reciprocation axis.

A dust collector for use with a hand-held power tool includes a housing, a suction pipe coupled to the housing, and an electric motor positioned in the housing. The dust collector additionally includes a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe, and a depth stop assembly. The depth stop assembly is configured to limit the axial movement of the suction pipe. The depth stop assembly is configured to be alternately positioned on opposite sides of the suction pipe in a first configuration and a second configuration, respectively.

Dust collector assembly

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and an upper blade guard covering an upper portion of the saw blade. The miter saw also includes a cut line indicator coupled to the upper blade guard. The cut line indicator includes a light source, a cover positioned between the saw blade and the light source, a housing in which the light source is positioned, a rib coupled to one of the cover or the housing, and a first slot defined in the other of the cover or the housing. The cover includes a second slot through which light from the light source passes to illuminate opposite sides of the saw blade and a work piece supported upon the base assembly, thereby casting a shadow of the saw blade onto the work piece. The rib is receivable within the first slot to align the second slot with the saw blade.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw arm, a brushless motor supported by the saw arm, and power electronics positioned outside the motor for supplying power to the motor. The power electronics are coupled to a structural component of the miter saw to utilize the entire mass of the structural component as a heat sink to dissipate heat generated by the power electronics.
