Cross Drill Bit

Cross Drill Bit

Standard thread/taper interface is compatible with various domestic and foreign rock drills, taphole drills and furnace dismantling machines, easy to install and disassemble.

Cross symmetrical blade design ensures no deflection during drilling, with excellent centering performance and high roundness of drilled holes, especially suitable for high-precision drilling such as blast furnace taphole opening.

Cross Drill Bit

Cross Drill Bit is a classic and widely used rock drilling tool, adopting an integrated welding/inlay structure of cross-type carbide blades + high-strength alloy steel body. It features sharp cutting edges, stable centering and steady cutting performance. It is mainly used for blast furnace taphole opening, mining drilling, geotechnical drilling and kiln maintenance, matching pneumatic rock drills, hydraulic rock drills and blast furnace taphole drills. It performs excellently in crushing medium-low hardness rocks, refractory materials and slag, making it a cost-effective and widely applied general-purpose drill bit.
