ABSTRACT:
A suction grip for holding a pneumatic power tool to the surface of sheet material for drilling and counterboring holes contains a plate and a releasibly fastened cylindrical member. The plate contains a shallow region on a front face that abuts the work surface and serves as a vacuum region. The cylindrical member contains a hollow passage that receives, alternately, an alignment tool to center that passage over a locator hole in the worked material and to support a self collating pneumatic drill for drilling the worked material. A collection of collars which may be interchanged on the plate serves as a kit, permitting use with different drills.
