Optimize your short-stroke and restricted-space drilling with the compact HLX1 R28 D28 255 shank adapter. Precision-engineered as a direct replacement for HLX1 series lightweight hydraulic drifters, this 255mm striking bar features a standard R28 thread and a slim 28mm diameter. Fully carburized to ensure high-efficiency impact wave transmission in narrow-vein mining and light roof bolting.
Key Performance Advantages
Precision R28 Threading: CNC-machined to exact industry tolerances, the standard R28 connection provides seamless coupling and easy uncoupling, optimized for small-diameter hole drilling.
Lightweight Slim D28 Body: Weight-matched to perfectly synchronize with the HLX1 small-piston impact cycle, preventing premature piston face damage and protecting internal seals.
Premium Wear & Fatigue Life: Full-body carburization and rigorous hardening create a "glass-hard" surface layer to withstand friction, backed by a resilient core to absorb cyclic shocks.
Primary Applications
Narrow-Vein Mining: Precision small-diameter blast-hole drilling and drifting in tightly restricted gold, silver, or base metal veins.
Light-Duty Roof Bolting: Ideal for light-duty underground utility hanging and rock bolt installations in restricted space profiles.
Specialized Utility Drilling: High-efficiency penetration for micro-piling, scaling, and architectural consolidation.
