As a factory-sourced part, the is manufactured to the same specifications as the original, ensuring a direct, trouble-free installation. This Tool Bush is confirmed to fit the EH 6 M/230, EH 6 M/115, EH 6 M/120, EHB 7 M/230, EHB 7 M/115, and EHB 7 M/120 breaker models.

Key Features
- OEM-Matched Bore Tolerancing — Manufactured to Wacker Neuson's original dimensional specs, so the tool shank seats and retains correctly without play or excessive wear.
- Direct Drop-In Installation — Replaces the original Tool Bush in the same position with no rework to surrounding components.
- Broad EH 6 M and EHB 7 M Compatibility — Fits the full range of EH 6 M and EHB 7 M electric breakers across 115V, 120V, and 230V configurations.
- Sustains Chisel Retention and Impact Transfer — A correctly functioning Tool Bush keeps the chisel firmly guided during operation; a worn bush allows unwanted movement that reduces strike efficiency and accelerates chisel and barrel wear.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number 5100034544 used in factory assembly and authorized service.
The Tool Bush is the precision-fitted sleeve that guides and retains the chisel or breaking tool inside the breaker's barrel. It holds the tool in correct alignment during each impact cycle, ensuring energy is transferred efficiently from the piston to the working tool. When the Tool Bush wears or fails, the tool becomes loose in the barrel — leading to misdirected impacts, accelerated wear on surrounding components, and reduced breaking performance.
