IRWIN 19-piece HSS metal drill bit set.

The IRWIN 19-piece HSS metal drill bit set (reference 01-2569) offers a comprehensive range of sizes from 1mm to 10mm in 0.5mm steps, covering most common metal drilling needs. Each bit is made from high-speed steel (HSS) with a 135° split point that ensures precise starting without walking, reducing the need for center punching. The fully ground flutes provide efficient chip evacuation, while the black oxide finish adds corrosion resistance and reduces friction.

This set is ideal for drilling into ferrous and non-ferrous metals such as steel, aluminum, brass, and copper. The bits are suitable for use in hand drills, drill presses, and CNC machines. The included metal storage case keeps the bits organized and protected, making it a practical choice for workshops and professionals. With its precise sizing and durable construction, this set delivers reliable performance for repetitive drilling tasks.
