Faithfull Dry Diamond Core Bit 157 x 150mm FAIDCD157

This is the largest diameter in Faithfull's range of dry diamond core bits, measuring 157 x 150mm. It is designed for heavy-duty commercial, industrial and civil engineering work, such as large-scale drainage systems, ventilation installations and utility penetrations through brick and concrete blocks. It also suits plumbing, electrical and general building installations where clean holes are required.

The bit features a 1/2in BSP threaded core with 8mm fluted turbo cut diamond segments in a V-groove design, which helps clear debris efficiently and provides good wear resistance during extended use.

It is for rotary use only and must not be used in percussion/hammer mode. Given its size, it should be used with a purpose-built core drilling machine, or a power drill of 850 watts or more fitted with a safety clutch and variable speed function, rather than an SDS Plus drill.
