Key Features
- OEM Material Specification — Manufactured to Husqvarna's exact material and dimensional tolerances, delivering the compression and sealing integrity required for core drill motor applications.
- Direct Drop-In Replacement — These sealing discs install directly into the designated sealing positions on compatible DM-series drill motors, matching the original mounting configuration without alteration.
- Broad DM-Series Compatibility — Fits the DM700, DM280, DM406, DM540i, DM540iKIT, DM230, DM400, and DM430 concrete core drill motors, covering a wide range of Husqvarna's professional drilling lineup.
- Protects Internal Motor Components — Properly functioning sealing discs prevent moisture, slurry, and debris from migrating into the drill motor's internal assemblies, preserving bearing and gear life.
- Fluid Containment Integrity — Worn or damaged sealing discs can allow lubricant loss or contaminant ingress; replacing them restores the motor's designed fluid barrier and prevents premature internal wear.
Sealing discs form a critical barrier within the drill motor assembly, isolating internal components from the wet, abrasive environment typical of concrete core drilling. They prevent water and slurry — which are constantly present during wet-core drilling operations — from reaching bearings, gears, and other precision parts inside the motor. When sealing discs degrade or fail, contaminants can enter the motor housing, accelerating internal wear and leading to more significant mechanical damage over time.
