The Husqvarna 544398801 Gear Wheel is a genuine OEM component designed for the DM330 concrete core drill. Sourced directly from Husqvarna, this gear wheel meets the original engineering specifications for the DM330, ensuring correct meshing, torque transfer, and dimensional fit. DHS Equipment supplies this part to help keep your core drilling equipment running at full capability.
Key Features
- OEM-Matched Tooth Geometry — Manufactured to Husqvarna's original gear profile, ensuring correct mesh engagement and load distribution specific to the DM330 drive train.
- Exact-Fit Replacement — Engineered to the same dimensions and bore tolerances as the original, allowing straightforward installation within the existing gear assembly without alteration.
- Designed for the DM330 Concrete Core Drill — Purpose-built for this drill motor, cross-reference part number 544398801 against your DM330 parts diagram to confirm fitment before ordering.
- Restored Torque Transmission — A correctly functioning gear wheel maintains consistent rotational force to the drill spindle, preserving core drilling speed and bit performance through demanding concrete applications.
- Genuine Husqvarna Quality — As an OEM part, this gear wheel is produced from the same materials and to the same hardness specifications as the original, supporting long service life under the high-load conditions of core drilling.
The gear wheel is a critical drive component within the DM330 drill motor's gearbox, transmitting rotational power from the motor to the drill spindle that drives the core bit. It works in mesh with adjacent gears to step down speed and multiply torque, allowing the drill to apply the sustained force needed to cut through reinforced concrete and masonry. When a gear wheel wears or loses teeth, the result is slippage, irregular spindle rotation, and loss of drilling efficiency — conditions that can also accelerate wear on surrounding gearbox components. Replacing a damaged gear wheel with a genuine OEM part restores proper drive engagement and protects the integrity of the full gear train.
