Learn Internal Thread Machining | M24×3 CNC Threading

Learn how to machine an M24×3 internal thread on a CNC lathe. This video shows the practical process of internal threading, tool setup, cutting conditions, and thread inspection for precision machining.

M24×3 is a metric coarse thread with a 3 mm pitch. For a typical tapped hole, the reference drill size is around Ø21 mm, while the basic internal thread minor diameter is about 20.75 mm.
