Optimize your short-stroke and confined-space drilling with the compact HC40 R32 D45 270 shank adapter. Specifically engineered for HC40 series hydraulic rock drills, this ultra-compact 270mm striking bar features a standard R32 thread and a robust 45mm diameter. Fully carburized to ensure perfect linear energy wave transmission and exceptional resistance to bending and fatigue in underground roof bolting and drifting.
Key Performance Advantages
Reinforced D45 Cross-Section: Despite its short length, the robust 45mm body diameter provides superior resistance to bending and shearing stresses, maintaining perfect stability within the chuck.
High-Precision R32 Threading: CNC-machined to strict international tolerances, the R32 connection offers seamless coupling and easy uncoupling, optimized for light-to-medium rock bolting.
Advanced Metallurgy & Fatigue Life: Full-body carburization and intense shot peening introduce high compressive stress, creating an ultra-hard exterior shell to withstand front-head bushing friction, backed by a ductile core.
Primary Applications
Roof Bolting & Ground Support: Essential drilling consumables for underground rock bolt and roof anchor installation in confined spaces.
Narrow-Vein Mining: Precision blast-hole drilling and drifting in restricted tunnel profiles.
Civil Anchor Drilling: High-efficiency penetration for specialized micro-piling and geological consolidation.
