Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact dimensional and material specifications, ensuring the retainer ring seats and holds under the operational loads of a core drill.
- Secure Component Retention — Engineered to lock internal components firmly in place, preventing axial movement that can cause accelerated wear or assembly failure during drilling.
- Direct Replacement for DM406 — Designed specifically for the DM406 concrete core drill, this ring installs into the correct groove position without modification.
- Restored Structural Integrity — A worn or missing retainer ring can allow internal components to shift under load; replacing it restores correct assembly alignment and protects surrounding parts.
- Verified Part Fitment — Use part number 531119036 to confirm this is the correct ring for your DM406 before installation.
A retainer ring is a small but critical fastening component that holds rotating or sliding parts in their correct axial position within an assembly. In a core drill like the DM406, it prevents internal components from migrating under vibration and drilling load, which could otherwise cause premature wear on adjacent parts or lead to assembly failure mid-job. When a retainer ring becomes deformed, cracked, or dislodged, the components it secures lose their positional constraint — making timely replacement essential to maintaining the drill's performance and protecting the broader assembly.
