Suitable for Montabert HC95sa rock drill, impact piston part number 86749124.

Impact Piston (86749124) – Suitable for Montabert HC95SA Rock Drill

The Impact Piston (Part Number 86749124) is a specially designed, high-durability component for the Montabert HC95SA rock drill. It is responsible for delivering the high-frequency, high-energy percussive blows necessary for efficient rock breaking in demanding drilling operations.

Description

Operating within the rock drill’s hydraulic system, the impact piston strikes the shank adapter with powerful, rapid impacts, transferring energy directly to the drill bit. This component is made from high-strength, wear-resistant alloy steel, providing excellent resistance to extreme pressure, high temperatures, and continuous impact forces.

Its precision-machined surfaces and balanced geometry ensure smooth movement inside the cylinder, consistent energy transfer, and reduced vibration — which collectively extend the life of the piston and surrounding drill components.

Key Features

• High-Strength Alloy Steel Construction – Exceptional impact and wear resistance for extended service life.

• Precision Machining – Guarantees a precise fit and smooth, efficient percussive motion.

• Optimized Balance – Ensures even energy distribution and reduces mechanical stress.

• Wear-Resistant Surface Treatment – Enhances durability under continuous high-impact conditions.

• Consistent High-Performance Impact – Maintains reliable striking force for improved drilling speed and efficiency.

Applications

• Percussive Rock Drilling – Provides powerful impacts to the shank and bit, fracturing hard rock.

• Mining and Tunneling – Suitable for continuous, high-demand drilling operations.

• Heavy Construction and Quarrying – Delivers reliable performance in tough, abrasive environments.
