Abstract
12,204. Blacklock, J. Aug. 24. Drills, cutters, and cutter-bars; reamers.- For counter-sinking holes, for example on the side of a plate remote from the operator, a tool of the detachablecutter type is employed. A cutter b of the shape shown is a friction fit in a slot in a bar a, which may either be a reamer as shown, or may have the end formed as a drill, or may be plain. The cutter is reversible and may be inserted in place after the passage of the bar through the hole to be countersunk. To relieve the bearings of a portable drill from the effect of a pulling-stress, the shank of the tool is fitted with a ball-bearing attached by a screwcap to the machine.
