DeWalt SPINDLE SA - N438748

Genuine DeWalt Spindle Assembly — Part N438748

Restore the front drive of your DCD796 / DCD797-series drill with this genuine DeWalt spindle assembly (part no. N438748). The spindle assembly is the precision-machined rotating shaft that the keyless chuck mounts to — it transfers torque from the gearbox to the chuck and replaces worn or damaged spindle/drive interfaces to stop wobble, slipping, or poor engagement.

Key details

- Part number: N438748. Referred to in parts diagrams as "Spindle SA".

- Function: complete spindle assembly for the drill’s front drive (direct replacement for the original spindle).

- Fits DeWalt Drill / Driver models : DCD796 , DCD796D2W , DCD796E1T , DCD796E2T , DCD796NT and DCD797

- Compatibility note: these drills use a keyless all-metal chuck with a chuck capacity of 1.5–13.0 mm; this spindle is the correct assembly for that front-end configuration.

Why this part

- Direct-fit replacement that restores correct chuck alignment and drive engagement without modifying the tool.

- Supplied as the spindle assembly (ready to install into the drill’s gearbox assembly) — ideal when the chuck still fits but rotation is off, the chuck wobbles, or internal spindle components are worn.

What’s included / what to check

- This listing is for the spindle assembly (N438748) itself — confirm your drill model/type matches one of the listed DCD796 / DCD797 variants before installation. Refer to your model’s parts diagram when replacing the spindle.

If your DCD796 / DCD797 has a loose or misaligned chuck, swapping in this original DeWalt spindle assembly will return the correct fit and rotation for the factory chuck and restore normal performance.
