Abstract

1303539 Drills A FISCHER 23 March 1970 [29 March 1969 19 Sept 1969] 13929/70 Heading B3C [Also in Division F2] A drill for drilling a hole in a wall and then anchoring a wall plug, comprises a bit 3, Fig. 1, having cutting edges 4, a tapered projection 9, and wedges 6, the bit being adapted to be driven by a shank 12, and when the hole is completed the shank is withdrawn, and a wall plug (20), Fig. 4 (not shown), is driven on to the wedges of the bit. Bit (11), Fig. 2 (not shown), has a drilling section that is thinner than its wedge portion (2). In a modification, the wall plug (28), Fig. 4 (not shown), also provides the drilling shank. In a further-modification, the bit has projections 109, Fig. 6, which are located in recesses 141 of the shank 119, Fig. 9. Projections 109 may be integrally cold pressed on the bit, or they may be stamped thereon.
