Review on Unleash Your Drilling Potential with BeHappy Titanium Plastic Aluminum Drilling - A Game-Changer in Precision and Efficiency by Steve French

These are not very good drill bits but for the price I knew I would get it. Since getting the package I've used them on both wood and metal, small bits will break in wood if you're not careful and even large bits have trouble with metal. In terms of price, it's still a good deal. If you need a reliable set for professional work look elsewhere, but if you just want to toss around a set of whisks for projects at home that you don't want to use a good set for, this is what you need.
