Dynamic runout (in) ADO Advanced Performance Coolant–Through Carbide Drill Stable Drilling with Long Drills The runout of a gripped cutting tool increases with 0.0393 the speed, as shown in the graph on the right. To ensure a higher level of work stability, OSG 0.0031 recommends "making +0.0008”-0.0031” (+0.02- 0.08mm) pilot holes" and "inserting long drills 0.0023 stopped or at low speeds." 0.0015 0.0011 0 The reason for this is made evident in the graph 0.0007 0.0003 on the right. Increasing the speed increases the 0.0007 0.0015 dynamic runout, posing a higher risk of the drill not 0 1,000 3,000 5,000 fitting properly in the pilot hole. Therefore, this is RPM (min-1) effective not only for inhibiting static runout, but is also the recommended drilling method for long Static runout drills.
