Abstract
5226. Wood, J. B. March 3. Boring and drilling.-A hollow boring head or bit, for boring or drilling holes from the solid, has a drill point or cutter A, Fig. 1, on its front end, thus dispensing with the opening-out of the hole necessary in using an ordinary D-bit. The cutter A is secured to a hollow head B either by a dovetail slot, as shown in edge-view in Fig. 2, or by screws C, as shown in Fig. 4. The head is detachably mounted on a hollow bar E and is guided in a bush F carried by a stay H. The drill A has grooves in its cutting-faces, to break up the shavings, so that they may be discharged through the head and an aperture G in the bush by the action of soapy water supplied through holes D.
