BBC35 Flat Face Rock Cutting Head
Our most popular cutting head, the Barbco BBC35 Flat Face Rock tunnels through mixed soil conditions with ease. Its unique flat design keeps the cutter bits free from debris and build-up during the auger boring process. Manufactured with top quality A36 steel, we’ve reinforced the 1-1/2” thick plate with a second layer for an impressive 3”-thick frame, adding integrity and durability to the tool. It’s equipped with two banks, each comprised of two rows of cutters to ensure a 100 percent cutting pattern. The head’s cutters, lead bits, over cutters and hex drive are all replaceable, so you can maximize your return on investment. Optional head leads are available, and all of our cutting heads can be sold with extra banks.
NOTE: BBC35 ROCK HEAD IS RATED AT 5000 PSI MAX. ROCK HARDNESS
