Abstract
In an advantageous embodiment, an apparatus comprises a housing associated with a machine, a shaft, a sleeve, and a biasing system. The shaft is associated with the housing, and the shaft has an end configured to receive a tool. The shaft is configured to be rotated by the machine about an axis of rotation extending through the shaft. The sleeve is associated with the housing, and the sleeve has a channel that is configured to receive the shaft. The biasing system is associated with the housing and configured to move the sleeve along the axis of rotation against a workpiece on which a drilling operation is performed during which a sleeve end presses against the workpiece with a force while the shaft with the tool is rotated by the machine.
