The 86484771 front guide housing bolts onto the Montabert HC109 rock drill. It's the front shell that holds internal parts in place and gives you a solid mount for the flushing and cuttings discharge pipe. CNC-machined from alloy steel to handle constant impact, vibration, and abrasive dust — the kind of punishment you see daily in mining, tunneling, and heavy construction drilling.

Part No. 86484771 – Suitable for Montabert HC109 Rock Drill
The Front Guide Housing, part number 86484771, is a front-end structural housing component designed for the Montabert HC109 rock drill. This housing section is located at the front of the rock drill body and serves as the connection interface for the flushing / cuttings discharge pipe, while also enclosing and supporting internal drilling components.
This front guide housing forms part of the drill’s outer structure and provides a rigid mounting point for the flushing and cuttings discharge system. It ensures correct alignment between the internal impact components and the external flushing pipe, allowing efficient removal of rock cuttings and debris during drilling operations.
Manufactured from high-strength alloy steel, the housing is designed to withstand high impact loads, vibration, and abrasive working conditions typical in mining, tunneling, and construction environments. Precision machining guarantees accurate fitment with the drill body and stable connection with the discharge pipe.
