Works great, drills through cast iron as smoothly as wood.
Hans Denzinger
The steel quality and sharpness are excellent. It drills four 4mm holes in a structural strip in 20 seconds without overheating or losing sharpness—great performance. I’d like to find larger screws from this brand too.
Klaus Carl
Excellent drill bit! It cuts through aluminum effortlessly and hasn’t needed resharpening yet.
Guenter Busse
It works decently. I didn't check the symmetry too closely, but it held up well when drilling through metal without damaging the edge.
