    摘要： A power tool for drilling a hole in a workpiece made of wood or a wood material. The power tool generally includes a tool housing defining a handle and a motor contained within the tool housing that includes an output shaft that spins about a motor axis. A gear housing is connected to the tool housing. An output spindle is supported for rotation about a spindle axis in the gear housing. The spindle axis is disposed about ninety degrees from the motor axis. A gear portion on the output shaft is engaged to a gear portion on the output spindle. The motor and the gear portions are configured to rotate the output spindle at a speed in range from about five thousand revolutions per minute to about twenty-five thousand revolutions per minute. A cutting member is connected to the output spindle. The cutting member includes fluted cutting blades. A carriage assembly includes a base member and a head member connected by a first post having a first compliant member and a second post. The head member slides relative to the first and second posts and against a force exerted by the first compliant member when the head member is moved toward the base member to pass the cutting member through the base member to engage the workpiece. The base member includes a generally planar face on a bottom surface of the base member that is generally perpendicular to the spindle axis.
