Rotating insert takes a drilling but stays fresh

To reduce tear-out at the bottom of holes drilled at my drill press, I added a sacrificial insert to my drill-press table. Nothing new about that idea, but I put a new "spin" on my version, so I could drill into the insert many times before having to replace it. By making the insert circular and offset from the bit, I simply rotate the insert whenever one spot becomes too worn, and then resume drilling into a fresh area.
