quality product, worked as expected would buy again

### ⭐⭐⭐⭐⭐ Drilled a hole in stainless steel as advertised!
*by J***S on July 30, 2026*

As advertised, this made short work of drilling a new hole in a stainless steel sink. I was a bit skeptical when ordering however it worked really well and looks like it will continue to be usable for some time. If drilling a lot of holes in stainless this is probably not the ideal tool but for the occasional work it knocked it out of the park. Recommended!
