Abstract: A rotary cutting tool has a cutting insert clamped from behind by a backing clamp against a frontal abutment defined in the body of the rotary cutter head. The clamp backs the cutting insert against the cutting pressure during operation and provides for the use of a same rotary cutter with different profiles of cutting inserts. Plugs of predetermined weight can be inserted in pre-formed holes in the cutting insert to permit recalibration of the insert after a sharpening operation.

Abstract: A spiral profile cutting tool for cutting a profile in a wood piece comprises a body defining an axis of rotation. Typically, at least two cutting blades are provided on the body. The cutting blades extend radially from the body about the axis of rotation in a spiral formation and have a variable radius defining a cutting profile for shaping a profile in the wood piece.

Abstract: A rotary cutting tool wherein the positioning of a cutting insert is accomplished via a frontal reference surface instead of a backing reference surface. This is done by modifying the regrindable insert to include a pair of lateral shoulders that must be seated on the reference surface to ensure proper positioning of the insert relative to the cutting tool. The insert is retained against centrifugal dislodgment by the frontal reference surface during rotation of the tool, thereby permitting the latter to be operated at higher rotational speeds. The use of a frontal reference surface also eliminates the need of having to reposition the cutting tool vis-à-vis the workpiece between each sharpening operation of the cutting insert.
