# Expo Handbook: Rigging guide - power drilling a bolt hole

Wookey demonstrating the technique of drilling a hole for an anchor with the Bosch cordless rotary hammer drill. Note that he is using both hands on the drill, so must be securely wedged in place using feet and/or the rope. Since it was given to CUCC in Sponsorship in 1990, the power drill has proved particularly useful on pitches where many rebelays are needed, and especially on bolted climbs or traverses such as "Three Wise Men". The drill was in such demand for this type of rigging that a second one was bought (and a third may be borrowed...)
