    • A pneumatic feed drill has a control unit that repeatedly advances and retracts the drill bit in peck cycles while drilling the hole. The drill has a hydraulic damper cylinder with a damper rod protruding from it that limits the speed of advancement of the drill bit. A retainer device is mounted to the damper rod and prevents the damper rod from resetting to its initial position during the peck cycles. The retainer device releases the damper rod to reset when the drill bit has reached total depth. A safety device is pivotally mounted to the housing and has a closure tab that blocks access to the start button of the drill unless the damper rod is in its initial position.
      The various optional features may be used in combination with one or more other optional features unless this is not possible.
    • 气动进给钻具有一个控制单元,可在钻孔时重复地将钻头前进和后退。 该钻具有一个液压阻尼器气缸,带有从其突出的阻尼杆限制了钻头的前进速度。 保持装置安装在阻尼杆上,并防止阻尼杆在啄圈期间复位到其初始位置。 当钻头达到总深度时,保持装置释放阻尼杆以进行复位。 安全装置枢转地安装到壳体上并且具有闭合突舌,该闭合突舌阻止对钻头的启动按钮的接近,除非阻尼杆处于其初始位置。 各种可选特征可以与一个或多个其它可选特征结合使用,除非这是不可能的。
