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. With higher penetration, straighter holes, longer service life and lower cost per meter drilled than integral steel, tapered drill equipment is grabbing market share from integral drill steel, especially in mining applications and the dimensional stone industry. Acedrills taper drill rods comes with three grades, and lengths available from 600mm (2) to 11, 200mm (368"), (measured from the collar to the tapered end).
