--- You wrote: When I bought some Johnson Carbide was the supplier, and I was told they supplied Steinway. That was ten years ago. It is important to get reamers with enought cutting flutes. It is possible to buy two-fluted reamers, but you need more than two cutting edges to obtain a clean round cut by hand. --- end of quote --- The reamers from MSC Industrial Supply have four flutes. They are $10 each, compared to Pianotek's $20. You can order them in increments of 0.0005". That is, you can get 0.049, 0.0495, 0.050", etc. The item description is:"HSS special decimal size straight flute chucking reamers". Phone for MSC: 800-645-7270.
