*The charts above display the maximum theoretical allowable rotation for optimal hole conditions. The RPM limits above are for optimal hole
conditions and normal drilling conditions and parameters. These should be reduced further when operating with high vibration, high rotary
torque, poor hole quality, high WOB, stick slip, hard stall events and other abnormal conditions.
