摘要

A drill stand includes a base plate, an elongated guide column extending outwardly from the base plate and a drilling device movably supported on the column. The guide column is formed of two laterally spaced elongated support members each having the same cross-section transversely of the elongated direction. A drilling device is positioned between the two support members. A rack is secured to the guide column and a feed mechanism for moving the drilling device includes a pinion in meshed engagement with the rack. Guide members on the support members fit into correspondingly shaped guide grooves on the drilling device.
