Rock Cutters
KRC 140 Bullhead Design Drum Cutter
The Kemroc KRC 140 Bullhead Design Drum Cutter offers superior cutting efficiency and precision for tough excavation tasks.
The KRC Range of bullhead cutters have two cutter drums arranged at an angle to one another so that the two sets of picks provide full face coverage without any gap between them, eliminating the need to swing the cutter from side to side. Operating the cutter without sideways movement creates a trench with the same width as the cutter Attachment.
Compared to the EK range of chain cutters, which also have full-face coverage thanks to the central cutter chain, the KRC range of bullhead cutters are easier to maintain. However, due to their design, they cannot achieve the extreme narrow trenching widths of the EK chain cutters.
