Genuine Makita 326188-1 — Anvil M. A precision-machined steel anvil assembly listed in Makita parts diagrams as "ANVIL M" (part no. 326188-1), intended to replace a worn or damaged drive anvil in Makita impact drivers.

Compatible with several Makita impact-driver models (for example DTD/BTD series such as DTD129RFE / DTD129RME and BTD129Z / TD126D); check your tool’s parts breakdown to confirm fit before installing.

Made from hardened, precision-machined steel for reliable bit retention and impact engagement — Makita’s hammer-and-anvil components use a specialized heat‑hardening process to resist wear under high‑torque impacts.

The anvil uses the standard 6.35 mm (1/4") hex drive interface common to these drivers, so replacing the anvil restores secure bit seating and reduces wobble or slippage.

Installation is straightforward — the drive-end assembly is accessed and the anvil is swapped in after removing the retaining ring and associated small parts, following the tool’s service diagram.

This part is listed in Makita parts listings and diagrams as a direct replacement when the anvil shows wear.
