    • 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.
    • 在有利的实施例中,设备包括与机器,轴,套筒和偏置系统相关联的壳体。 轴与壳体相关联,并且轴具有构造成接收工具的端部。 轴构造成由机器围绕延伸穿过轴的旋转轴旋转。 套筒与壳体相关联,并且套筒具有构造成容纳轴的通道。 偏置系统与壳体相关联,并且构造成使套筒沿着旋转轴线移动抵靠在其上执行钻孔操作的工件,在该工件期间套筒端部用力将工具压靠在工件上,同时工具的轴旋转 机器。
