Key Features
- Genuine OEM Specification — manufactured to Husqvarna's exact dimensional and material tolerances, ensuring the ring seats and functions as originally designed in the DM406 drill assembly.
- Direct Assembly Fit — engineered as a drop-in replacement that aligns with existing mounting points and mating components, requiring no rework or modification to adjacent parts.
- DM406 Compatibility — sourced specifically for the DM406 concrete core drill; cross-reference part number 531111055 with your machine's parts diagram to confirm the correct application.
- Structural Integrity Restored — replacing a worn or damaged ring returns the assembly to its correct operating clearances, preventing premature wear on surrounding components.
- Long-Term Assembly Stability — an OEM-grade ring maintains proper load distribution and alignment within the drill, supporting consistent performance during demanding core drilling applications.
A ring component in a concrete core drill typically serves to retain, seat, or seal adjacent parts within a mechanical assembly — maintaining correct clearances, preventing unwanted movement, and protecting mating surfaces from wear or contamination. When this component becomes worn, distorted, or damaged, surrounding parts can shift out of alignment or suffer accelerated wear, leading to degraded drilling performance or potential damage to the drill assembly. Installing a correctly specified OEM replacement restores the mechanical integrity of the assembly and supports the continued performance of the DM406 in demanding concrete drilling conditions.
