### ⭐⭐⭐⭐⭐ Excelente calidad-precio

### ⭐⭐⭐⭐ You get what you pay for
*by J***N on 11 September 2025*

Just drill bits. Nothing special.

### ⭐⭐⭐⭐⭐ Unexpected quality! I'll buy again.
*by B***N on 17 September 2024*

I had gone through 3 HSS black cobalt jobber bits (also from Amazon), drilling through 1/4" mild steel brackets prior to switching to these bits. A single bit did the work of the prior 3 bits combined, and it is still almost as sharp as new. A very unexpected and pleasant surprise. I would definitely buy this product, from this vendor, again.
