QCTP Drill Parallelism Adjustment in Round CNC

30 June 2026

In this How-to-Use video, we demonstrate how to check and adjust the drill parallelism on the QCTP using a dial indicator.

Drill parallelism is a crucial setup step for accurate drilling operations on desktop CNC lathes. Correct drill alignment helps to reduce runout, increase hole accuracy, and achieve more consistent machining results.

During this process, the drill's position is checked with a dial indicator, and the necessary fine adjustments are made on the QCTP tool holder.
