💡 What is the optimal spindle velocity for diamond core bits on glazed ceramic and poured concrete?

Keeping the motor throttle steady stops the brazing joints from cracking while advancing the cutter smoothly.

- Maintain three thousand rotations per minute for fast penetration through soft mortar and light block

- Reduce to two thousand RPM on dense quarry tile or reinforced slabs to dodge microfractures in the glaze

- Feather the trigger so the handy alignment guide seats flat before committing to straight downward force
