I had to drill through a stainless steel sheet, actually the license plate holder on my Ducati. I tried some cheap drill bits I had at home but there were no dice. Bosch cobalt drills went through. I did a little research and learned how to use the drill at a lower speed and it worked like clockwork. These are high quality drill bits that are important when working with very hard materials like stainless steel. This is a great product.
