I ordered this set for two reasons. Firstly it was a full span of 16 bits and secondly it had hex shanks for the big bits. Anyone who has turned large drill bits on a drill press can tell you that hex shafts cost an extra dollar or two. I got what I expected. For a small amount of around $4.50, these aren't high-end tools. As with all low-to-mid range woodworking tools, this price is due to the lower quality of tool processing. Expect burrs on the cutting edges and grinding marks on the inside. It takes less than 2 minutes to level the edge with a file and then sharpen it. These beats will still save you money unless you're getting paid A LOT per hour. As you can see they do an excellent job on oak and other hardwoods, especially after sharpening. A small number of outbreaks in fir and pine. As you would expect the pine is soft and I used a hand drill. Overall I am satisfied with this set. All budget instruments need a bit of polishing to make them what you want, they appear to be decent steel and a fair price.
