“THE” Hammer “The Kovai 6" class hammer performs excellently at all depths. In my (36) years of hard rock drilling experience, I feel it is quite possibly the fastest penetrating hammer on the market today!!” Jeff Franco Wellco Drilling, Inc. Raymond, CA 408-431-6000 kovaidrills.com “We recently had a multiwater well project near Pinnacles National Park, east of Soledad, CA. The lithology consisted of upper sandstone and decomposed granite followed by hard, weathered granitic rock. Prior to the Kovai hammer with 7.5" bit, we were averaging 140' per day with 6" button bits and drill collars and various other hammers. Once we switched to the Kovai hammer, our production increased to 120' per hour average. With auxiliary air, we were able to reach 660' on multiple holes that were producing in excess of 60 gallons per minute. We look forward to Kovai launching larger hammers and we appreciate their local distributorship and assistance.” Augie Guardino Guardino Well Drilling, Inc.
