BBC26 Combo Head with Rock Piercing Dirt Cutters

How many times have you encountered rock on a dirt bore? Push through with a combination cutting head. Offering exceptional strength and versatility, the Barbco BBC26 Combo Cutting Head excels at cutting through dirt and chewing through soft rock formations. To build the cutting head, we start with a 1-1/2” thick A36 steel plate and reinforce it with a second piece of steel to create a solid, 3”-think frame. Comprised of two banks of rock piercing dirt cutters and lead bits, we offer replacement parts for those, the over cutters and hex drive, so you can maximize your return on investment. Customize your cutting head to fit your project needs. We offer optional head leads and extra banks.
