Original Makita 412556-5 — Hammer/impact case cover designed to restore the hammer section of compatible Makita impact wrenches. This replacement cover mounts to the hammer/impact housing with the factory screw and locating-pin pattern so it lines up with the internal hammer and anvil assembly; it’s sold as a single cover and intended to replace cracked or damaged hammer housings on the tool.
Fits (examples): XWT15-series impact wrenches and Makita DTW300 / DTW301 / DTW302-style models — listed as the hammer/impact housing or hammer case cover for these tools. Use this original Makita part when you need a direct-fit Makita parts replacement to get your impact wrench back to factory alignment.
Why this part helps: a worn or broken hammer case cover can allow debris and oil into the hammer mechanism or let the internal components shift — replacing it restores correct alignment and keeps the hammer components protected. This is a genuine Makita hammer case cover intended for repair work and is one of the small, commonly replaced parts you’d look for when ordering parts for power tools.
