This is by far, the very best and highest quality drill bit set I have ever owned. Unlike other bits I have encountered, these bits stay sharp and get the job done. They are ideal for drilling through steel and iron plates leaving sharp, clean holes every time. The warranty is also great - break a bit and they will replace it free of charge. Warranty card is inside drill box. While I'm praising the bits, let me also acknowledge that the drill bit storage box is really nice too. Yes, it's plastic, but the quality stands out from other brands as well. The bit clamps actually "hold" the bits tightly in place while stored, and the closure mechanism is top of the line too. I am NOT a paid reviewer or someone who got the product so I would review it. These are my actual assessments of this product. I just felt strongly enough about it to let others know what a great product it is and give STROTON their deserved credit.
