Holman drill, lantern slide
Holman cradle-hammer drill. The C.H 10 is a new drifter on the lines of our well-known Cradle-Hammer Drill (C.H.2) with the weight reduced to 120lbs and with many minor improvements. The chucks can be supplied to take either shanked, or unshanked steel, square, hexagon or cruciform. It is an all steel Drill with a drop forged cylinder and valve chest. The C.H 10 does not supersede the C.H2 it is designed for lighter work, where the conditions do not neccessitate the terrific hitting power of the Drill.
