Abstract
A flexible cutting tool includes a substantially cylindrically-shaped housing having a first end and a second end. The first end includes a hollowed region. A substantially cylindrically-shaped bushing, having a first face and second face and including a flexible material, is sized such that the first face and at least a portion of the bushing are secured inside the hollowed region of the housing. The bushing includes a bore extending through the first face, the second face, and an axis of the bushing. A cutting tool includes a cutting edge, a stop, and a shaft between the cutting edge and the stop. A diameter of the stop is larger than a diameter of the bore for allowing the stop to enter the second face of the bushing, frictionally pass through the bushing and exit the first face of the bushing. A diameter of the shaft is smaller than the diameter of the stop and larger than the diameter of the bore such that the bushing frictionally engages the shaft. A length of the shaft is longer than a thickness of the bushing. A flexibility of the cutting tool is a function of an amount of the shaft extending from the second face of the bushing.
