This adapter converts a 1-1/4" UNC male output to a HILTI BL-type female interface, allowing standard coring machines to be used with HILTI-compatible core bits or accessories.
The H-BL side features internal drive teeth to securely engage with HILTI BL drill tools.
Made from heat-treated alloy steel with black oxide finish, it ensures reliable performance under high-torque concrete coring applications.
