The Husqvarna 544124001 Bar Friction Disc is a genuine OEM replacement designed for the DM225 concrete core drill. As an authentic Husqvarna component, it is manufactured to the exact specifications required for proper operation of the drill's feed and torque control system. DHS Equipment supplies this part to help keep your DM225 running at full capacity. Cross-reference 544124001 against your parts diagram to confirm fitment before ordering.
Key Features
- OEM Friction Material Grade — manufactured to Husqvarna's specified friction coefficient and surface finish, ensuring consistent torque transfer without slippage or glazing under load.
- Exact Dimensional Match — machined to the original bore, outer diameter, and thickness tolerances so this disc seats correctly against the bar assembly without shimming or adjustment.
- Confirmed Fitment for the DM225 — engineered specifically for the DM225 concrete core drill; verify against your machine's parts diagram using part number 544124001.
- Restored Feed Control Performance — a correctly functioning bar friction disc maintains smooth, controlled feed pressure during core drilling; a worn disc causes erratic feed, bit chatter, and premature core bit wear.
The bar friction disc is a critical torque-limiting and feed-control component within the drill's drive bar assembly. It works by applying calibrated frictional resistance to regulate the force transmitted to the drill bar, preventing overload and allowing the operator to maintain steady, controlled penetration through concrete. When this disc wears or glazes, feed pressure becomes inconsistent, increasing the risk of bit binding, core deviation, and unnecessary stress on the drill motor — making timely replacement essential to maintaining drilling accuracy and protecting the wider drivetrain.
