The DF545 HD T38 D45 515 shank adapter is a high-performance striking bar engineered for the Doofor DF545 series hydraulic rock drills. Featuring a T38 thread, 45mm diameter, and 515mm length, this heavy-duty (HD) version is designed to withstand the rapid impact cycles of high-frequency drifters, ensuring optimal energy transmission in tough rock conditions.
Why Choose the DF545 HD T38 D45 515?
Engineered for High-Frequency Impact: Doofor hammers are known for their high strike frequency. Our DF545 HD shank is manufactured using special fatigue-resistant alloy steel to prevent stress cracking during long-duration drilling.
Precision T38 Threading: The T38 thread is CNC-machined to ensure a tight, low-vibration connection with T38 drill rods, significantly reducing the "thread heat" that causes premature wear.
Enhanced D45 Stability: The 45mm diameter (D45) provides a robust cross-section that prevents the shank from flexing, protecting the front-end bushings of your Doofor drifter.
Premium Surface Hardness: Through an advanced carburizing process, we achieve a hard, wear-resistant surface shell (HRC 58-62) while maintaining a core that can absorb the massive shock loads of modern tunneling jumbos.
Primary Applications
The DF545 HD T38 D45 515 is widely used in:
Tunnelling & Drifting: Precision blast-hole drilling for road and rail tunnels.
Surface Drilling: Small to medium hole production in quarries.
Bolting: Reliable performance for underground roof bolting rigs.
