Single Jack Rock Drilling – 50th Annual World Championship

50th Anniversary - Rock Drilling Contest - Nevada Day
We're hosting the 50th Annual World Championship Single Jack Rock Drilling Competition

The 50th Annual World Championship Single Jack Drilling Contest is taking place this year. Contestants use 4 1/2 pound hammers and a 3/4″ bit of steel to drill as deep and fast as they can in a 4,320 pound piece of Sierra White Granite. They have 10 minutes to drill and their only help is from an assistant who runs water into the hole to clear out loose stone chips. The deepest hole wins.
