Abstract:
A cutting tool includes an outer tubular member having a first magnet and an inner tubular member having a second magnet wherein the inner tubular member is slidably disposed within the outer tubular member. A force, such as an attractive force, is created between the first magnet and the second magnet. The attractive force creates a preload force between the inner tubular member and the outer tubular member. A method of creating a force between an inner and outer tubular member is also disclosed.
