Piano tech part# AR-12 used in a pin vice does a great job of cleaning and polishing the hole. with correct geometry. The less pressure you use on the tool the more polished the surface. Pianotech #2332 is used to counter bore the agraffe to set the correct angle and elevation. In combination with .010" brass shims. It's a tedious job, but well worth the effort. No Zings, and better string levelling. Regards Roger
