Tackle solid rock bores with strength and precision. The shape of the Barbco Christmas Tree Rock Cutting Head helps the machine self-center to maintain line and grade accuracy. One of our heavy duty cutting heads, this style is constructed using 1-1/2” thick A36 steel plate with three or four bank heads. Each bank features an over cutter and a wiper mounted with 1” GR8 hardware. After some wear and tear, you can easily replace the over cutters, hex drive and bits for extended use. Optional head leads are available.
