Starting with patented labyrinth cuttings exclusion to protect the seal, Avenger combines patented seal surface textur- ing, conical seal gland geometry, and heat shield to provide long, reliable oper- ation. Patented bearing pres- sure reduction enhances reli- ability in rough or f ractured ground. T h e s e game-chang- ing bits are the culmination of innovation and careful study of bit performance in mining applications. The result: A high- performance tool with patented advance- ments in bearing and seal technology, patented shirttail protection, and cus- tomized for purpose cutting structures. This mixture of technologies improves ROP (rate of penetration), lowers total drilling costs, and extends life where conventional air-cooled roller bearings struggle. Avenger series bits push the bound- aries of performance through the inclusion of patented EdgeGuard Shirttail Protection. This design helps avoid the traditional trade-off between bearing package size and shirttail protection. The technology deploys patented tungsten carbide plates along the shirttail, which maximizes the protection of the seal and bearing with- out constraining bearing capacity. This premium shirttail protection, combined with Varel’s exclusive Sidewinder cuttings evacuation system, provides longer runs and more reliable performance. This effort was the result of years of experience from the company’s field engi- neers and experts, along with Varel’s capa- ble roller cone engineering group. Using best practices across their product lines, designers were able to incorporate tech- nology already proven through success- ful execution in the oil and gas product area. The Avenger series bits support the Varel Mining & Industrial group's line of roller cone offerings. The company is committed to lead- ing innovation in the industry by pushing bit design farther and faster to provide the best bit possible. Combined with qual- ity customer service, Varel International is proud to live their motto every day, “Dedicated to Drill Bits!” 0&"2'*3) 02*, 0&"2'*3) /,*%"9 ..
