BBC50 Roller Cone Rock Head

The Barbco BBC50 Roller Cone Head is engineered for optimal performance in hard rock ground conditions, giving contractors the cutting power and durability they need for a wide range of trenchless applications.

Built with heavy-duty roller cones, the BBC50 is a rigid and highly durable cutting head designed to withstand the demands of underground construction. Available in sizes from 12-84″, it provides contractors the flexibility to match the right tool to the right job. With cutting capabilities up to 20,000 psi, the BBC50 delivers reliable results in challenging ground conditions.

To ensure maximum performance and cutter longevity, the BBC50 must always be run with water to keep the cones cool during operation. This precaution enhances efficiency and extends service life, making it a trusted choice across the trenchless industry.
