42 Large and small wrenches

This drill bit is centered on "lightweight, high efficiency, and precise adaptation", and is specially designed for small and lightweight drilling scenarios. The key parameters are clear Compatible with 42 drill pipes, the overall weight is only 3.2KG, and it is made of high-strength alloy material. It not only meets the requirements of operational flexibility but also has excellent impact resistance and wear resistance, making it a perfect match for lightweight operation scenarios such as shallow hole drilling in small-scale mines and rural infrastructure drilling. Its core advantage focuses on solving construction pain points: First, the balanced design of material and weight. The 3.2KG lightweight body enables single people or small teams to easily carry and operate it without relying on heavy auxiliary equipment, making it suitable for site restrictions such as rural areas and small mines. High-strength alloys can withstand the impact and friction during drilling, reducing drill b…
