3 Wings Step Drag Bit With (190mm) 7 1/2'' x 3 1/2'' API REG Pin For Coal Mining

Product Introduce

Drag bits are economical tools when drilling softer geological formations and shallower depths. We supply both step drag bits and chevron drag bits. Chevron drag bits are usually used for drilling more abrasive formations like soft sandstons and shales. Chevron drag bits are more durable than step drag bits because of cutting structuer, but penetrate more slowly.

Adavantages

Each of our bits is machined from a forging to exacting standards and then tipped with tungsten carbide.Mining grade tungshen carbide tips are brazed to the bit wing face for heavy duty bits.The pin thread are CNC manufactures and wings surfaces hardening subsequently.
