Key Features
- Genuine OEM Specification — Manufactured to Husqvarna's exact tolerances, ensuring the key seats correctly within the shaft and hub without play or slippage.
- Drop-In Replacement — Matches the original profile and dimensions exactly, allowing straightforward installation without machining or fitting adjustments.
- Broad Drill Compatibility — Confirmed fit for the DM1PACE, DM280, DM340, and DM650 concrete core drills, as well as the DM700 PRIME equipment platform.
- Torque Transfer Integrity — A correctly fitted parallel key locks the rotating component to the shaft, transmitting full torque without slippage — critical for consistent core drilling performance and accurate bore alignment.
- Protects Surrounding Components — Using the correct OEM-spec key prevents accelerated wear to the shaft keyway and mating hub, helping preserve the integrity of the wider drivetrain assembly.
A parallel key is a precision-machined component that sits in matching keyways cut into a shaft and a hub, locking them together so that torque is transferred evenly between the two. In a core drill motor, this small but critical part ensures the drive coupling or gear hub rotates in unison with the shaft under load. When a parallel key wears, shears, or goes missing, the shaft and hub slip independently, causing loss of drive, uneven boring, and potential damage to the keyway surfaces of both components.
