The end of the drill flutes had a small burr, recommend dressing it with a stone (or sandpaper) before using the drill bit. The same for the tap, the cutting edges look slightly rounded. But for the price they are a reasonable quality, and Im only using this in aluminum. The tap doesn't have much lead in taper, if you are using this every day I would suggest a higher quality tool.
