Drifter RD18U 8311128801 is a high-performance core component for Hydraulic Rock Drills. It’s engineered to meet the demanding rock drilling needs of underground mines, open-pit quarries and construction sites.
As the “power heart” of hydraulic rock drills, it directly determines drilling efficiency. It also influences rock-breaking capacity and equipment service life. It solves key industry pain points: low drilling speed, high energy consumption and frequent maintenance.
Crafted with high-grade 42CrMo alloy steel for the cylinder body. The impact piston is made of tungsten carbide for exceptional durability. It delivers 18kJ of impact power and a precise 35Hz impact frequency. This enables fast drilling of rock with compressive strength up to 250MPa.
Its advanced hydraulic control system optimizes oil flow distribution. It reduces energy consumption by 28% compared to standard drifters. Performance remains stable even in continuous operation.
The drifter’s surface undergoes nitriding treatment and anti-corrosion coating. It passed 100-hour salt spray tests. It resists moisture, abrasive debris and harsh mining environments.
Drifter RD18U 8311128801 features a modular design with precision-machined internal components. It ensures smooth coordination between the impact piston and valve core. A shock-absorbing buffer structure is integrated. It mitigates vibration during high-frequency impact. This extends the service life of paired drill rods by 35%.
Each unit undergoes strict ISO 9001 quality verification. Tests include impact power measurement, durability trials (≥50,000 drilling cycles without failure) and 3D scanning for dimensional accuracy.
It offers seamless compatibility with mainstream Hydraulic Rock Drill models. This includes Atlas Copco FlexiROC T45, Sandvik DP2000 and generic brands. Installation is straightforward with a bolt-on design. It matches original equipment mounting points—no custom modifications needed. This minimizes maintenance downtime for mining teams.
Backed by a 12-month warranty, it’s a cost-effective investment for mining and construction firms. It boosts drilling efficiency by 40% and reduces operational costs. Whether used for deep underground drilling or large-scale open-pit mining, Drifter RD18U 8311128801 ensures reliable impact performance. It enables fast rock breaking and long-term operational stability for Hydraulic Rock Drill systems.
