The counter sink is not used to drill holes. It is used to provide a "bevel" on the circumference of a drilled hole.

This bit did a decent job with countersinks, but it's not for applications that require a high degree of accuracy. Running it in a cordless drill, I found it wandered quite far off center the deeper I got. This was mitigated somewhat by drilling a wide diameter pilot hole, but there was still some degree of "wander". The only time I'd use this in the future is in a drill press. A closer inspection of the bit shows a dull point and uneven grinds on the cutting edges. I'm pretty sure this is contributing to the bit's tendency to move off center during drilling. I tried both hard and soft woods with the same result. The good news is I didn't experience any chattering while using it. Overall, I'd try a different HSS bit, since this one is a little more expensive than other comparable bits that come with a more consistent grind.

Multi Material Capability
This high-speed steel countersink, of Chinese manufacture, is intended for use with wood, metal or plastic. The five cutting flutes provide a reasonable finish. I used it to countersink a ½ inch diameter hole in pieces of; PVC, Oak and Steel. It performed best in steel. PVC required judicious control of the bit speed to avoid overheating the material. The countersink left a little bit of a “fuzzy” edge on the oak piece. In steel, the countersink knocked down the “ridge” left by the drill bit, and provided an acceptable surface, with the 82o included angle. The five cutting flutes did not “load up” even in PVC (if care was taken not to go too fast).

So far a very good bit
I have only had a chance to use the 5/8 in. High Speed Steel Countersink by Ryobi bit a few times but so far I am happy with it. I did a few test countersinks in wood and all had a very clean, smooth walls. It also worked good in metal but you have to remember to use a lubricant or you will ruin the bit. All five cutting edges are very sharp and being made from high speed steel should last for a long time. This bit is made to work on wood, metal and plastic.
