4 wings chevron drag bits
4 wings chevron drag bits are one piece construction of alloy steel cast with tungsten carbide cutting tips and gauge sides to ensure longer life. It has 4 wings and 4 flushing holes. 4 wings chevron drag bits are more durable and lasting than 3 wings chevron drill bits, because of cutting structure, but will penetrate more slowly. Additionally, 4 wing chevron drag bits are more stable and tend toward drilling a straighter hole.Its flushing hole is incorporated into our design for efficient removal of cuttings.

4 wings chevron drag bits are economical tools when drilling softer geological formations and shallower depths, they are primarilydesigned for medium to hardformation and areused in areas thatcontain a lot ofrock, such as hard shale, limestone, and tougher gravels, etc. And also chevron drag bits are recommended for drilling in Mining, Exploration, Environmental, Water well, Geo Exchange, etc.
