Original DeWalt bevel gear N406771 — a precision-machined metal bevel gear designed to redirect the motor’s rotary motion at roughly 90° to the drive shaft, restoring smooth torque transfer in affected rotary/hammer drills.

Compact replacement dimensions: approximately 48.3 × 47.0 × 16.5 mm (length × width × thickness), sold as a single bevel gear ready to drop into the existing gear housing and mesh with the pinion.

Example fitment — commonly used in DeWalt rotary and hammer drill models such as D25333K, D25334K and the DCH-series models (DCH283, DCH293, DCH323, DCH333, DCH334) including the common Type/X2 variants; check your tool’s parts breakdown and part number N406771 for confirmation before installing.

If you keep parts for power tools on hand, this genuine DeWalt bevel gear is a direct, like-for-like replacement to get a damaged gear train back to reliable operation without replacing larger assemblies.
