Larger runout will influence drill performance and hole quality.3 In case of a stationary application, clamp the drill in an orientation that directs both outer cutting points parallel to the machine%u2019s X-axis.4 On stationary (lathe) applications, if there are misalignment problems use alignment devices such as the ISCAR /ETM GYRO device. 5 The SCDT %u2026-M%u2026 drills are recommended to be clamped into ISCAR tooling systems such as:%u2022 SHORT-IN collet chuck adapters with AA super precision%u2022 Power chuck adapters%u2022 Hydraulic adapters%u2022 Shrink collets or adapters
