ISO CE certificatied 4 wings chevron drill bits for Big Diameter Mining / Water Well Srilling

Application                                                                                                                                                         

4 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 has4 wings and 4 flushing holes. 4 wings step drag bits, are more durable and lasting than 3 wings step drag bits, because of cutting structure, but will penetrate more slowly. 4 wing step drag bits are more stable and tend toward drilling a straighter hole, as its 4 wings have more stable structure and do not make a deviation in the drilling.
 
4 wings step drag bits are economical tools when drilling softer geological formations and shallower depths, they are primarilydesigned for soft tomedium formations, such as Clay, Loam, Silt ,Mostsoft-to-medium soilsthat have some moisture, etc. And also step drag bits are recommended for drilling in Mining, Exploration, Environmental, Water well, Geo Exchange, etc.

1. A solid one piece heat treated, 4140 alloy steel body for bit strength & durability;
2. CNC threaded machining for proper installation &use;
3. Forgings are milled to better seat the carbide inserts.
4. Select tungsten carbide inserts 5.5mm thick are standard.
5. Relief is hand ground behind carbide inserts for maximum performance.
