SPIRAL PROFILE CUTTING TOOL
摘要:
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.
