M03 turns the spindle on in the clockwise (CW) direction.

M04 turns the spindle on in the counter-clockwise (CCW) direction.

M05 stops the spindle, and waits for it to stop.

Spindle speed is controlled with an S address code; for example, S5000 commands a spindle speed of 5000 RPM.

If your machine has a gearbox, the spindle speed you program determines the gear that the machine uses, unless you use M41 or M42 to override gear selection. Refer to M41 / M42 Low / High Gear Override for more information on the gear select override M-codes.
