a versatile drilling tool designed for creating precise holes in materials such as metal, wood, plastic, and other machinable materials. Its standard length provides a balance of strength, stability, and accuracy, making it suitable for general-purpose drilling applications. Manufactured from high-quality high-speed steel (HSS) or alloy steel, the bit offers excellent durability, wear resistance, and efficient cutting performance. The 3.5 mm medium drill bit is widely used in engineering, fabrication, maintenance, automotive, and workshop environments where reliable and accurate drilling is required.
