Basic Info.

Product Description

The drag bit is the earliest type of drill used in rotary drilling. The drag bit has a simple structure. On the elliptical cylindrical housing with internal thread, a lateral working blade is welded, and the blade is welded with a sheet-like carbide cutting. With the blade warning, the surface of the working surface is welded with a flaky, cylindrical carbide cutting tool and a granular cemented carbide.

Stepped three-wings drag bits are suitable for medium-hard to hard formations, as well as for rocks and oil fields. drag bit is divided into two-wing drag bits, three-wing drag bits, four-wing drag bits and so on

1.All Bits are one piece construction of alloy steel forged or cast with Carbide cutting tips and gauge sides to insure long life through the toughest drilling formations.

2.All Carbide tips are silver soldered to the bit wing by a special process to insure a strong bond that will not shear or break when drilling through the hardest Rock.

3.Because of the large flow course, the drag bit is suitable either for air or fluid drilling and does not subtract from the bits strength .

4.Number & shape of cutting blades/stones

5.Size and location of the water courses

6.Metallurgy of the bit and cutting elements
