Key Features
- Genuine OEM Material Grade — manufactured to Husqvarna's original hardness and dimensional tolerances, so the washer absorbs friction and load exactly as intended for this application.
- Direct Drop-In Replacement — engineered to the same profile and thickness as the original, this wear washer seats correctly without modification to the surrounding assembly.
- Confirmed Fitment for DM650 and DM700 — validated for Husqvarna's DM650 and DM700 concrete core drills, eliminating guesswork when sourcing a replacement.
- Protects Mating Surfaces — by absorbing wear between contact faces, this washer shields harder structural components from premature surface damage, extending the service life of the surrounding assembly.
- Restore Proper Drilling Performance — a worn or missing wear washer allows excessive play and uneven load distribution, which can affect drilling accuracy and accelerate wear on adjacent parts. Replacing it restores correct operation.
A wear washer acts as a sacrificial friction buffer between two moving or loaded surfaces within the drill assembly. By taking on the wear that would otherwise be absorbed by harder, more costly structural components, it helps maintain proper alignment and smooth operation during core drilling. When a wear washer deteriorates, increased surface contact between metal parts can lead to accelerated wear, vibration, and reduced drilling precision — making timely replacement an important part of keeping your DM650 or DM700 core drill performing correctly.
