Product Description

Product Description

three wing step drag bit for water well drilling and borehole drilling
 

three wings step drag bits are one-piece construction of alloy steel cast with tungsten carbide cutting tips and gauge sides to ensure longer life. It has 3 wings and 3 flushing holes. Compared with 4 wings, 3 wings step drag bits tend to drill faster and aggressively, whereas, are shorter lasting and less durable.3 wings step-style drag bits will produce larger cuttings force than chevron style drag bit. The rotary table speed of step drag bits should be between 60 and 80 rpm with a lightweight on-bit (WOB).

three wings step drag bits are economical tools when drilling softer geological formations and shallower depths, they are primarily designed for soft to medium formations, such as Clay, Loam, Silt, Most soft-to-medium soils that have some moisture, etc. And also step drag bits are recommended for drilling in Mining, Exploration, Environmental, Water well, Geo Exchange, etc.

Step type bits are the most common type of drag bit used widely for soft to medium formations. Step-type drag bits are very effective in drilling soft and unconsolidated material. They are available in a full range of sizes from 3" to 17 1/2".The design of step-type drag bits provides for fast drilling penetration and requires only moderate drilling weight for proper operation. A large center flushing hole is incorporated into our design for efficient removal of cuttings
