DeWalt 1006725-00 — original DeWalt shim washer engineered for the SDS‑plus rotary hammer impact assembly. This thin, precision spacer sits in the hammer / ram stack to set the correct axial clearance so bearings, seals and the impact mechanism run true and the tool maintains smooth hammer action.

Fits a range of DeWalt DCH-series rotary hammers — examples include DCH143, DCH243, DCH253, DCH254, DCH273 (Type 1 and some Type 2 variants), DCH274, DCH363 and DCH364 — match the part number 1006725-00 to your parts diagram to confirm fit.

Sold as the single shim washer used in the factory assembly, it’s the exact DeWalt replacement you want when restoring correct spacing inside the gearbox / impact train during a repair. This is a small, high-tolerance metal washer intended for use with related power tool parts in the DCH rotary‑hammer family.
