Long lasting drilling in tough metals
- Premium Bosch cobalt construction: The high-grade HSS-CO steel allows you to drill through stainless steel and tough metals with superior heat resistance.
- Accurate split point tip: The 135-degree point prevents walking on smooth surfaces, letting you start drilling precisely without pre-punching.
- Impact resistant storage case: The durable Robust Line cassette keeps all sizes organized and protects your drill bits from jobsite drops.
With the Bosch pro RobustLine hss-co metal drill bit set, you drill cleanly and accurately through stainless steel, alloyed steel, and tough metals. Thanks to the premium cobalt-alloyed high-speed steel, these bits offer outstanding heat and wear resistance, significantly extending tool life during demanding metalworking jobs. The self-centring 135-degree split point prevents bit wandering on smooth surfaces, allowing you to start drilling instantly without centre punching. This 13-piece set covers diameters from 1.5 to 6.5 mm and comes in an impact-resistant RobustLine cassette, keeping your drill bits organized, well protected, and ready for every job site challenge.

- Long service life when drilling stainless steel
- Long service life when drilling in stainless steel
- Cobalt alloy and fully ground HSS ensure wear resistance and heat resistance
Advantages
- Long service life - The HSS spiral drill bit cobalt lasts a long time when drilling in stainless steel.
- This longer life is due to the steel alloy containing 5% cobalt and the fully ground HSS (High-Speed Steel), which offers excellent surface quality, wear resistance and heat resistance.
- Thanks to two cutting edges and two grooves, chips are quickly removed, making the drill bit last even longer.
- This drill is suitable for alloyed and unalloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steel.
- This drill bit is suitable for alloyed and unalloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steel.
- The drill has a cylindrical shank (drill and shank have the same diameter) and is intended for use in drill stands and drill/screw machines.
- The set comes in a practical ProBox for convenient and safe storage and transport of the drill bits Cylindrical shank compatible with three-claw drill chucks.
