A biscuit cutter is provided for cutting an arcuate slot in the edge surface of a workpiece. The biscuit cutter is made of a base, a drive motor, a rotary cutter blade and an adjustable fence. The base is provided by the first planar surface having an elongated slot through which the rotary cutting blade is positionable when a plurality of extended positions corresponding to a selected one of a plurality of predetermined sized biscuits. The adjustable fence has a second fence surface for engaging the workpiece and has a centerline indicia and a plurality of slot length indicia spaced about the centerline indicia for providing a visual indication to the user of the length of the slot to be formed in the workpiece for each of the plurality of biscuit sizes.

Biscuit cutter

A biscuit joiner for engaging a workpiece to form a slot sized to receive a carpentry biscuit is provided. The biscuit joiner has a base with a fence surface for engaging the workpiece. The fence surface has an elongated opening formed therein. A motor is fixed to the base, and has a drive shaft. A link has a first end pivotally mounted to the base, and a second end rotatably mounted to a rotary cutter blade. A drive mechanism connects the drive shaft to the rotary cutter blade. An actuator is operable to pivot the link relative to the base. Pivoting the link causes the rotary cutter blade to shift relative to the fence surface between a retracted position in which the rotary cutter blade is within the base, and an extended position in which the rotary cutter blade extends through the elongated opening in the fence surface to cut the workpiece. Alternatively, a slidable carriage is received on the base. The motor and rotary cutter blade are mounted to the carriage. The carriage is slidable relative to the base toward and away from the fence surface. The actuator is operable to slide the carriage to cause the rotary cutter blade to shift between the extended and retracted positions.
