Eastern Driller's Mfg. Co. introduces its newest 6-inch down-the-hole hammer, the BB6, the company's fastest hammer to-date. The hammer is designed to run efficiently on as low as 750 cfm and higher; it uses a bit with the QL shank. The BB6 is said to be durable enough for the gas and oil fields, fast enough for the quarries and dependable enough for water well drillers. Eastern Driller's Mfg. Co., Card No. 313
