Professional FESTA step drill bit made of quality HSS steel with a TiN coating for smooth and precise drilling of holes 4–20 mm. Offers 9 steps, high durability and service life, and reliable chip evacuation thanks to wide flutes. Ideal for alloys, steel sheets up to 4 mm, as well as plastic and wood.
The FESTA HSS 4–20 mm step drill bit with Titanium Nitride (TiN) surface treatment is designed for fast, clean, and controlled drilling of various diameters without changing tools. The TiN coating significantly reduces friction, increases cutting edge durability, and extends the overall service life of the bit.
Thanks to 9 precisely defined steps, you can create holes from 4 to 20 mm with a smooth transition and minimal burrs. Wide flutes efficiently remove chips, improving cooling and cutting stability. Suitable for alloys and steel sheets up to 4 mm thick, as well as for plastic and wood.
Main advantages:
- 4–20 mm range in one tool – 9 steps for universal use.
- TiN coating – higher hardness, lower friction, longer service life.
- Quality HSS steel per DIN 1412C – precise and clean drilling.
- Fast chip evacuation thanks to wide flutes – smooth operation without jamming.
- Universal use – alloys, steel sheets up to 4 mm, plastic, wood.
