23CrNi3Mo H22 Tapered Hexagonal Drill Rod with 4°46'/7°/11°/12° Taper for Mining and Quarry Drilling (400-8000mm)
Tapered drill rods are designed for shallow hole drilling operations using small pneumatic or hydraulic rock drills. Manufactured from H22 and H25 hexagonal hollow drill steel, these rods are engineered to work with taper drill bits for rock drilling applications in quarries, coal mines, roadbeds, and construction projects.
Available with standard taper angles of 7°, 11° and 12°, the selection depends on the rock type and drilling environment for optimal performance.
- Superior durability through carburize treatment for long-lasting performance
- Engineered to transfer percussion energy efficiently from rock drill to drilling bit
- Withstands high bending stress and tough drilling conditions
- Resistant to corrosion from flushing hole water exposure
- Manufactured with high-quality materials for extended lifespan
