专利汇可以提供Adjustable drill on attachable base专利检索，专利查询，专利分析的服务。并且A base has means by which it is attached to a workpiece to be drilled with one portion of a dovetail slide thereon which cooperates with the other portion of the dovetail slide on the frame which supports the drill unit. After the base is secured on the workpiece, the frame and drill unit may be moved forwardly or rearwardly along a longitudinal plane. The base may be provided with a pivoted section which has the one portion of the dovetail thereon so that after the base is clamped to the workpiece, the drill point may not only be adjusted longitudinally but also sidewardly so that it may be located exactly over the point at which drilling is to occur. This permits the base element to be attached to the workpiece with the drill point in approximate position or adjacent to a plurality of positions after which it may be located over the point or points on the workpiece at which drilling is to occur.，下面是Adjustable drill on attachable base专利的具体信息内容。
