The Husqvarna 577758201 Sealing Ring Holder and Clamp Kit is a genuine OEM assembly designed for the DM650 and DM700 concrete core drills. As a factory-sourced component, this kit delivers the exact material grade, dimensional tolerancing, and compression characteristics required to maintain a proper seal within the drill's water management system. Cross-reference part number 577758201 against your parts diagram to confirm fitment before ordering.
Key Features
- OEM Sealing Integrity — Manufactured to Husqvarna's original compression and material specifications, ensuring the sealing ring maintains the water-tight barrier essential to core drilling performance — something generic replacements frequently compromise.
- Complete Holder and Clamp Assembly — Supplies the full sealing ring holder and clamp together as a matched set, allowing a straightforward, like-for-like installation without sourcing individual components separately.
- Confirmed Fitment for DM650 and DM700 — Engineered specifically for the DM650 and DM700 concrete core drills, ensuring the assembly seats and clamps correctly within the original mounting configuration.
- Protects Core Drill Water Feed Performance — A correctly functioning sealing assembly keeps water flowing consistently to the drill bit, preventing overheating, premature bit wear, and loss of cutting efficiency on the core drill.
- Prevents Costly Leaks and Internal Damage — A worn or failed sealing ring allows water to migrate into unintended areas of the drill motor, risking internal corrosion, electrical damage, and unplanned downtime on the job.
The sealing ring in a core drill is responsible for containing the pressurized water feed that cools the diamond bit and flushes concrete slurry during drilling. The holder and clamp work together to secure the ring in position, maintaining consistent contact and preventing bypass leakage under the vibration and pressure of active drilling. When the sealing ring, holder, or clamp wears or cracks, water pressure drops at the bit, cooling becomes uneven, and moisture can work its way toward the motor housing — shortening both bit life and drill service life. DHS Equipment supplies this genuine OEM Sealing Ring Holder and Clamp Kit to help restore your DM650 or DM700 core drill to full operating condition.
