Import 770mm T45 Cop2160ex Shank Adapter — Buy in wholesale FOB from Supplier in China

The 770mm T45 COP2160EX Shank Adapter from Maxdrill Rock Tools is a precision-machined drill string component designed to transfer percussive energy from hydraulic or pneumatic drifters and top hammers to the drill bit. Its 770mm overall length and T45 thread configuration conform to established rock-drilling industry standards, ensuring compatibility with common drifter systems and extension rods. The COP2160EX designation indicates a specific shank dimension and chuck compatibility profile developed for Atlas Copco/Secoroc pattern equipment, a widely adopted standard in surface and underground production drilling.

Manufactured from alloy steel with heat-treated surfaces, this shank adapter endures the high-cycle fatigue and axial impact loads inherent in percussive drilling. The thread form is precision-cut to minimise galling and maintain consistent torque transmission across make-and-break cycles. Typical industry practice specifies surface hardness in the range 48-55 HRC for the shank body, with core toughness retained to resist fracture under bending stress. The female T45 thread mates with male T45 extension rods; the shank end interfaces with the drifter chuck to match the COP2160EX chuck profile exactly. Standard finish is anti-corrosion oil coating with protective end caps for sea freight.

This adapter serves mining contractors, quarry operators, tunnelling specialists and water-well drillers who run hydraulic top-hammer or drifter rigs. Buyers should confirm chuck compatibility (COP2160EX), thread condition on receipt and torque specification for initial make-up. The 770mm length suits standard feed arrangements on Atlas Copco ROC, Boomer and equivalent rig models. Importing from Maxdrill Rock Tools in Guiyang, Guizhou Province, buyers will need to verify thread gauge certification, material mill certificates and whether the supplier provides matching coupling sleeves or flushing adapters.
