Starting points from the same engines as the calculators, with no tool or setup picked. The first number is where to start; the range is what the manufacturer charts allow. Open a calculator for your tool, machine and cut.
Draft data: researched from manufacturer charts, not yet reviewed by a machinist.
Machining notes
- Very gummy: razor-sharp edges, high positive rake, lubricant.
