BBC95 Heavy Duty Combo Cutting Head
Tough bores require extreme strength. One of our most highly rated cutting heads, the Barbco BBC95 Heavy Duty Combo Head offers unmatched durability for hard rock bores. We first introduced this head on a boring machine tunneling head. Then a conventional version after seeing its exceptional cutting performance. Apart from the lead, all the cutters are mounted on the same plane to create a cutting pattern that exceeds 150 percent. We offer replacement parts for the cutters, lead bits, over cutters and hex drive. Optional head leads and drift reducing rings are available, and all of our heads can be sold with extra banks.
