Stability Tool Life The stability of the application volume is important in order Drills should not be used with flank to obtain the very best tool life and hole accuracy. Check wear exceeding 0.2-0.3 mm. the condition of the machine spindle, fixture and fixturing of the component to secure maximum stability and rigidity. Unstable conditions can cause tool breakage. 0.2-0.3 mm Max 0.02 mm Max 0.02 mm Correct Direction Incorrect Direction Stationary Drill Rotating Drill External Coolant External Coolant 583 583
