Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact material and dimensional specifications, delivering the same seating behavior and load distribution as the original component.
- Direct-Fit Replacement — engineered to install in the same position as the factory part on the DM220, requiring no modification to surrounding components.
- DM220 Core Drill Compatibility — specifically listed for the DM220 concrete core drill, so you can order with confidence that this is the correct part for your machine.
- Maintains Clamping Integrity — a correctly fitted washer distributes load evenly across the fastener interface, preventing fastener loosening and protecting mating surfaces under the sustained vibration of core drilling operations.
- Protects Surrounding Components — using the correct OEM washer prevents surface damage, deformation, and wear to adjacent hardware that an improperly sized or substituted part can cause over time.
A pressure washer in a core drill assembly serves as a load-distributing interface between a fastener and the surface it bears against. By spreading clamping force over a wider area, it prevents fastener pull-through, surface indentation, and premature loosening caused by vibration — all of which are common in the high-torque, high-vibration environment of concrete core drilling. When this washer is damaged, deformed, or missing, fastener integrity is compromised, which can lead to misalignment or damage to the components it secures within the DM220.
