    摘要: A power tool is provided including a tool housing in which an electric motor is disposed. The electric motor includes a stator and an armature rotatably received within the stator. The armature has an armature shaft on which a commutator is mounted. The power tool further includes at least one brush assembly disposed around the commutator, the brush assembly including: a brush having two grooves on opposites surfaces therein; a brush holder comprising two support plates arranged defining guiderails that extend into the grooves of the brush to facilitate movement of the brush along a single axis; and a spring contacting the brush that urges the brush radially inwardly along the axis.
