Here is a cool bit! This one is a bit older, with the older style makers mark, likely from when the company was being transitioned from Ervin Quick, Â who built bits for over 60 years, to his son Mike Quick. Despite this one being older, its in excellent condition. Shows just a bit of patina more from storage and time than actual use. Smaller 4 7/8″ alloy mouth, with rounded Segunda port that measures 1 1/2″. 8″ shanks. Loose jaw style. Nice feel to this one.
