Carbide Drag Bit is manufactured by casting high quality alloy steel and premium tungsten carbide insert, plus state of art welding technology and multiple precision heat treatment to provide highest penetration rate and longest life span at roughest condition. Widely used in the soft formation, such as sand, clay, and also some soft rocks in water well drilling and mining construction. We can supply carbide drag bit with step type and chevron type, carbide drag bit we have 3", 3 3/4", 3 7/8", 4 3/4", 4 5/8", 5 7/8", 6", 6 1/4", 6 1/2", 7 7/8", 8", 8 1/2", 9 7/8" with API standard thread. Except API thread carbide drag bit, we can also supply carbide drag bit with female thread, such as geological 50mm female thread, 2 3/8 reg female thread, 2 3/8 IF female thread etc. If you want high quality carbide drag bit from a water well drilling bit manufactuer with competetive price, welcome to contact us. What we can do is to provide carbide drag bits with different sizes and competetive price.
