The 86706819 retainer chuck is a key locking component designed specifically for the Montabert HC50 rock drill. Its main function is to firmly clamp the drill rod during operation, ensuring that it will not slide or fall off even under high impact drilling (4200 bpm). The chuck is made of wear-resistant hardened steel, which is the key to ensuring efficient drilling and safety of HC50 under harsh operating conditions.
