Our factory manufactures DIN340 standard HSS 4341 straight shank extended length twist drills, featuring a bright finish, suitable for drilling operations on iron, aluminum, wood, and various metal materials.
Made from 4341 high-speed steel, these drills possess moderate hardness and toughness, adapting to multi-material cutting needs—maintaining stable precision when drilling metal materials and achieving smooth chip evacuation in processing non-metallic materials like wood. The straight shank extended length design not only facilitates stable clamping with conventional drilling tools but also adapts to deep hole drilling scenarios, addressing the limitation of insufficient shank length in ordinary drills. The bright finish retains the original properties of the base material, reducing potential adaptation restrictions caused by surface coatings, and is suitable for working conditions with specific requirements for the drill’s surface state.
Strictly manufactured in accordance with the DIN340 standard, the products feature controllable dimensional accuracy and structural strength, widely used in fields such as mechanical processing, furniture making, and equipment maintenance. Relying on standardized production lines and strict quality inspection processes, our factory ensures the stability of bulk supply, providing customers with standard-compliant deep hole drilling tools suitable for multiple scenarios.
