It is quick and easy to install through fractured or broken ground. The system is available with a range of harder drill bits for efficient drilling in stronger material. T76 self-drilling bar system is a precision-machined combination anchor-drill of high-grade steel, specially tempered to insure clean, close-fitting holes and plated to resist rust and corrosion. Eight sharp cutting teeth quickly and accurately drill into masonry materials without fouling. T76 self-drilling bar system is a bolting solution for unstable ground conditions such as sand, gravel, silt, and clays, and in soft to medium fractured rock formations.
