Our factory supplies straight shank extended-length twist drill bits, compliant with the DIN340 standard, made of 4341 high-speed steel, suitable for drilling holes in materials such as iron, aluminum, and wood.
4341 high-speed steel features good hardness and toughness, adapting to the cutting characteristics of different materials—maintaining stable precision when drilling on metals like iron and aluminum, and achieving efficient chip evacuation in wood processing. The straight shank extended-length design not only facilitates stable clamping with conventional drilling tools but also adapts to deep hole drilling scenarios, reducing operational limitations caused by insufficient shank length.
The products are strictly manufactured in accordance with the DIN340 standard, with controllable dimensional accuracy and structural strength. They are suitable for scenarios such as mechanical processing and furniture making that require deep hole or regular drilling. Our factory can ensure bulk supply through a standardized system, meeting customers’ needs for compliance and practicality.
