I routinely polish, lacquer and ream agraffes when I restring, using the agraffe reamer from Pianotek (AR-12).
For the first time today I ran into a set of agraffes with a steel insert running horizontally through the agraffe immediately above the string holes. I have read in older posts that the steel is not necessarily much harder than the brass, so maybe I could ream as usual. However, it seems to make sense to me to throw the question out here on Pianotech before proceeding.
So here's the question. Will I regret reaming these agraffes in the way to which I am accustomed? Is there a better path forward?
The piano is a 1921 Nordheimer.
