A1: The drill bit bodies are made from high-strength 50R61 steel, and the cutting heads utilize premium YK05 or T6 grade tungsten carbide for maximum wear resistance.
A2: We offer 11 main thread types, including SR22, SR25, R25, SR28, R28, SR32, R32, SR38, R38, and T35 to ensure compatibility with most standard drilling rigs.
A3: Yes, our button and cross bits are designed with varying carbide configurations and body styles (standard and retrac) to optimize performance across different geological conditions.
A4: We maintain a high production capacity of approximately 50,000 pieces per month to ensure steady supply and timely delivery for large-scale projects.
A5: To prevent damage during transit, products are securely packed in either reinforced wooden cases or heavy-duty cartons depending on the order size and shipping method.
A6: Our cross bits are typically available in diameters ranging from 35mm to 57mm, though the broader drifting tool range supports diameters up to 127mm.
