Tapered drill equipment also provides a hexagonal chuck section to provide leverage for the rotation chuck bushing, which usually also has a forged collar to maintain the proper shank striking face position in the rock drill, and match a tapered bit at the socket end. Holes are typically drilled in 0.6 m increments to accommodate the air-leg feed length.
