Step-Type Drag Bits Of Three-Wings And Four-Wings For Water Well Drilling
Product Introduce
Drag bits can be either solid or welded construction. Solid, or one piece construction, is the most durable and recommended for all oil field and natural gas applications where error cannot be tolerated. Because of the large flow course, drag bit is suitable either for air or fluid drilling and does not detract from the bit's strength.
Adavantages
1.Drag bits are welded solid at the nose for durability
2.Forgings are milled to better seat the carbide inserts
3.Relief is hand ground behind carbide inserts for maximum performance
