PERFECT SIZE: For precise drilling of various sizes from 5–35 mm in diameter, one drill bit can process holes of different sizes.

QUALITY MATERIALS: Classic high-speed steel, titanium coating on the surface, suitable for drilling holes in aluminum plates with a thickness of 1–4 mm, also suitable for plastic and wood.

LASER ENGRAVING: The size is laser engraved into the metal, so it will not wear off even with reuse, facilitating precise drilling.

EASY TO DRILL: The marking hole position and the double groove design make drilling faster and smoother, ensuring precise drilling.

PRECISE POSITIONING DRILL: When you press on the surface, it generates an automatic impact force, high impact force, spring-loaded, and an adjustable hood allows the impact force to be adjusted. The knurled surface of the HSS body is very slip-resistant and allows for precise positioning points without fear of deviation.

With only slight pressure, holes are drilled automatically while you drill.

Ensures fast, smooth, and easy cuts. Clean, each step is clearly marked with the depth diameter.
