538. Taylor, F. W., and Newbold, S. Jan. 8. Boring and drilling; tool-holders.-Drills, reamers, countersinkers, and the like are provided with self-hardening cutters secured in holders by a fusible metal packing as described in Specification No. 5044, A.D. 1901. In the case of a boring tool, the holder is provided with slots A<3>, A<5>, Fig. 4, for the reception of the cutters B, C, Fig. 5. The side cutters B are of self hardening steel and the centre cutter C may be of tempered steel. The faces B', B<2> are adapted to engage each other and the bottom a<3>, A<4> of the groove A<3>, and the bottom C<1> of the cutter C beds on the projections b<2> of the cutters B. The cutters are assembled in the holder with those parts in contact, which are pressed together while at work, and the fusible metal is run in. Modifications applied to drills and countersinkers in which the cutters are in one piece are shown and described in the Specification.
