Testimonials
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!!
In the hard, abrasive iron ore at Mont-Wright Mine, the Kovai DTH hammer delivers excellent penetration with outstanding reliability. It handles tough conditions with ease and keeps our drilling efficient and consistent.
We tested Kovai DTH hammers against major brands in multiple quarries. They delivered strong penetration, reliable performance, and excellent service life in tough rock conditions. Based on their overall performance and durability, we adopted 5-inch and 6-inch Kovai hammers for our South Carolina drilling operations.
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
We've been using Kovai's 8-inch DTH hammer for the past two years, and it's performed very well in our water well drilling operations. It has delivered reliable performance while saving us money compared to some of the bigger brands. I'd definitely recommend giving Kovai a try if you're looking for quality and value
