Step Drill Bit designed from premium M35 high‑speed steel with cobalt delivers outstanding durability and wear resistance. This multi‑step drill effortlessly cuts a range of diameters (4.0–20.0 mm, 20.0 mm) in one tool, saving you time and eliminating the need to change bits between holes. It is ideal for drilling metals, plastics and wood for cleaner, more precise holes.
Featuring an advanced nano coating, this step bit withstands high temperatures and oxidation, allowing higher cutting speeds and extended tool life. The coating’s low friction helps chips slide away easily, enhancing cutting efficiency and preserving sharpness. As a result, you can drill harder materials without overheating or premature wear.
