RUKO krátky vrták DIN 1897 HSS TiN Ø11,0 mm

For machinists and metalworkers tackling shallow drilling in tight setups, the RUKO stub drill bit delivers rigid, accurate holes in steel, cast iron, and non-ferrous metals. Its short flute design reduces deflection, making it ideal for thin materials and portable drilling.

Why choose it

The TiN coating increases surface hardness and heat resistance, extending tool life and reducing friction. Ground from solid HSS, this bit offers high wear resistance and consistent performance in demanding materials.

Ideal use cases

• Drilling shallow holes in alloyed and unalloyed steel
• Creating precise holes in cast iron components
• Working with non-ferrous metals and plastics
• Applications requiring a short, rigid tool for improved accuracy

Good to know

The stub length provides enhanced stability compared to standard jobber drills, reducing the risk of breakage in handheld or CNC operations. The golden TiN finish is a visual indicator of the coating.
