STHOR Step drill bit set 3pcs. 22616
The Sthor 22616 step drill bit set is a high-quality tool that is ideal for drilling in stainless steels, structural steels, non-ferrous metals, steel plates and plastics. The set includes three drill bits with diameters: 4-12 mm, 4-20 mm and 4-32 mm, which allows you to drill holes of different diameters in a wide range of materials. The drills are made of HSS 4241 high-speed steel and coated with titanium nitride, which ensures their longevity and high cutting performance. Thanks to the self-centering on rounded surfaces and the rapid heat dissipation, working with them is comfortable and effective.
Key features of drill bits:
- Drill bit diameters: 4-12mm, 4-20mm, 4-32mm, ideal for drilling holes of different diameters.
- Made of HSS 4241 high-speed steel, ensuring high durability and wear resistance.
- Titanium nitride coated surface for improved cutting properties and longer tool life.
- Stepped in 2 and 3 mm increments, allowing different hole diameters to be achieved without the need to change the drill bit.
- Triangle chuck (3 flat surfaces) for a secure hold in the drill chuck.
- Self-centering on rounded and slippery surfaces, which prevents the drill bit from "escaping".
- Fast heat dissipation when drilling in hard materials, which improves work efficiency.
