Description
Belltec BHD Series auger bits are designed for difficult ground where ordinary dirt bits are prone to hanging up or wearing quickly. A patented severe-duty boring head, aggressive cutting geometry and 4.5-inch pilot help the bit advance through gravel, cobble and fractured rock.
The series is offered in diameters from 6 to 48 inches and in 48- or 54-inch overall lengths. Single- and double-flight configurations allow the tooling to be selected around hole size, spoil removal requirements and the available auger drive.
The bit diameter, connection, flight style and drive capacity must be matched to the carrier and ground conditions. Solaris can help select the appropriate configuration and verify compatibility with the customer’s drive system.
Product Support
To help you select a BHD bit, please share your auger-drive make and model, output-shaft connection, required hole diameter and depth, machine hydraulic capacity and a description of the soil or rock.
Verify drive torque and approved maximum diameter before use. Contact Solaris for compatible drive systems, replacement teeth and pilots, wear parts, configuration guidance and availability.
