Universal HSS step drill bit for precise drilling in thin sheet materials without pre-drilling. Delivers clean, burr-free holes and no chip buildup. Ideal for non-ferrous metals, thin-walled steel sheets, and plastics in the workshop and on-site.
The HSS 4–20 mm step drill bit with 9 clearly defined steps is designed for fast and accurate enlarging of holes in thin-walled materials. Thanks to high-speed steel, it offers long service life, a smooth cut, and minimal vibration.
Suitable for sheet-metal work, metalworking/locksmithing, plumbing, and other trades where a clean final hole is required without additional deburring.
- No pre-drilling: seamless enlargement of the hole in a single step.
- Clean edges: drilling without burrs and without clogged chips.
- Universal use: non-ferrous metals, thin-walled steel sheets, plastics.
- Precise stepping: 9 steps from 4–20 mm for flexible hole diameters.
