Bought to split wood, product didn’t split any of the logs I had. Just put holes in it.

Nice that it came in a case. No HSS markings on tool, making actual steel content suspect. Used with oil and low speed, still dulled quickly cutting though medium steel. Specifically at the 24mm depth. Other depths cut ok, but it will not last long.
