ريش الثقب المعدنية بوش قياس (4.5mm) المصنوعة من الفولاذ سريع القطع (HSS-G) المكونة من عشر قطع تباع (Per Pkt)

HSS stands for high-speed steel. It offers excellent durability, wear resistance, and heat tolerance, which helps maintain sharpness and performance when drilling metal.

They are versatile for drilling through common metals such as steel, aluminum, and iron. They’re optimized for metal projects rather than wood or plastic.

Key features include a precision ground tip for accurate starts, a robust surface finish to reduce friction, heat resistance for high-temperature drilling, and a standard 4.5mm size with a 10-piece pack for replacements.

Use a drill with an appropriate chuck, keep the bit cool with cutting oil or coolant, apply steady pressure without forcing, and drill at moderate speeds to prevent bit wear and ensure clean holes. Allow the bit to do the work rather than pushing hard.

Insert the bit into a properly tightened drill chuck and ensure it is straight before starting. After use, wipe clean and store in the provided case to prevent rust and keep the set organized.

Yes. The HSS-G 4.5mm bits are built for durability and performance, making them suitable for home projects and more demanding industrial tasks.

Wear eye protection, clamp the workpiece securely, avoid overheating by using coolant or cutting oil, start with a smaller pilot hole if needed, and keep hands clear of the rotating bit.

For similar metal drilling tasks, you can consider the 3.0mm and 5.0mm Bosch HSS-G sets to match hole size requirements. The 3.0mm set is best for smaller pilot and precise holes, while the 5.0mm set handles larger holes with similar construction and durability.
