High Quality Mining Carbide Tool DTH Button Hammer Bits Drilling Tools

High Quality Mining Carbide Tool DTH Button Hammer Bits Drilling ToolsProduct DescriptionKINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a spline drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.Rock drill bits Shank type:M3,M4,M5,M6,M8,M1,M12DTH hammer bits hole diameter: 3'', 4'', 5'', 6'', 8''(85mm-350mm). Product features: DTH Drill Bits are produced from premium quality nickel-alloy steel for increased durability and wear characteristics. Specific heat treatment standards and special "stress relief" processes ensure consistent performance.   Technical Date  3 Inch Hight Air Pressure DTH bitsModelBit Dia.(mm)NO.
