Review on 🔧 High-Performance Okamoto Grinding Adapter (HHIP 2420 0520) by Jesse Azuse

The cone fits my Boyer-Schultz 612 perfectly. My only complaint, and it's a small one, is that the threaded part used to remove it is slightly larger than the original. While a standard removal tool will likely work, you'd better make it suitable to avoid permanent damage to the threads of the adapter or tool.
