190mm 7 1/2'' Diameter AR 3 1/2'' Thread Blue Corlor 3 Wings Step Drag Bits
Product Introduce
Drag bits can be either solid or welded construction. Solid, or one piece construction, is the most durable and recommended for the applications where error cannot be tolerated.
All tungsten carbide tips are silver soldered to the bit wing by a special process to ensure a strong bond that will not shear or break when drilling through hard rock.
Features
Drag drill bit is used for drilling overburdens with sands, clays and soft formations. These bits will produce larger cuttings than a Chevron style bit.
Because the step drill bit is more aggressive than the Chevron, the effect will be faster. However, it will be less durable as well.
