The powerful impact, and ease of operation make the JOY Sinker an ideal shaft sinking drilling tool. The drill is useful for innumerable small surface jobs. (E.G. block-holing oversize in a quarry).
The SK60M is a 3 1/8" piston drill with a collared 4 1/4" by 7/8" hex chuck.
Fatigue is reduced by using spring mountings for the holding handle.
A front handle which doubles as a foot bar completes the ease-of-handling features of this light-weight yet rugged drill.
