There are four main models in Komatsu’s lineup today – namely the ZT44 (diesel, DTH, 24.4 m typical hole depth and 165 mm hole diameter), ZR77 (diesel or electric, DTH or rotary, 16.8 m typical hole depth and 251 mm hole diameter), ZR122 (diesel or electric, DTH or rotary, 19.8 m typical hole depth and 311 mm hole diameter) and the 320XPC (electric, rotary, 19.8 typical hole depth and 351 mm hole diameter).
