Has anyone here worked with diamond router bits / profile milling tools for shaping hard brittle materials like glass, ceramics, quartz, or technical composites?
Tool geometry and bond type seem to make a huge difference in edge quality, chip reduction, and overall tool life—especially on detailed profiling work.
This reference has a solid overview of different options and applications:

Curious what RPM, feed rates, or coolant setups others have found work best for getting clean profiles without edge chipping.
