I have a whole bunch of stakes intended for a 1 1/8" (one and one eighth inch) hardie hole but my anvils hardie hole is a tad too small - probably nominal 1".
Any suggestions for enlarging the hole before I spend an age with a grinder reducing all the stake shanks? It's too hard to file, and I've got nowhere fast with a carbide burr on an airdrill.
