Technical Note


Chisel-type hand crafts are one of the first hand tools of mankind. Additionally, they were used on early rock excavation machines as cutting tools when mechanical excavation machines had been newly developed. Since they had rather simpler geometrical shape, especially the simple-shaped ones, they provided a better understanding of rock cutting mechanism and led to the development of the rock cutting theories (Evans 1958; Potts and Shuttleworth 1959).

Rock cutting tools are divided into two subgroups, namely drag picks and roller bits. Simple-shaped chisel picks belonged to drag picks group along with complex-shaped chisel picks, radial picks, forward attack picks and, conical picks as seen in Fig.  1. Simple chisel picks, nearly, have no practical usage on rock cutting machines. These tools are only used on cutter heads of some drilling machines operated in low- and medium-strength rocks. Radial and forward attack picks are used on partial face machines such as shear...
