Applications: These core bits have extended barrels to drill into deep walls. They are especially useful in the walls of older building where the middle may be loose-filled. Once drilled through, the pipe can be inserted as the core bit is withdrawn to help avoid fall-back of the loose fill. They are also useful in the smaller sizes, where the adaptors would restrict the available drilling depth. They use standard dry core bit 1/2" BSP fittings. Use a power drill without hammer action and with a clutch or torque limiter. Ideal power would be 1kW or more, especially for the 107mm size.
