They matched the description. but I didn't get the smooth sanding or deburring I needed so I ended up not using it (1 out of 6 over 10 seconds) and went back. It really depends on the application you need them for. For my. Wrong application. For your. that could work great. I would recommend trying it. They approached my drill. but the post bit was round. I want them to be hexagonal or similar to better hit the drill. Much luck.
