About SMS R5 Mini - Multipurpose Rotary Head

SMS R5 Mini- Multipurpose Rotary Head

The SMS R5 Mini is engineered for drillers who refuse to sacrifice torque for portability. Weighing in at a lean 130 kg, this rotary head is the ultimate solution for multipurpose drilling rigs where space and weight distribution are critical, but performance is non-negotiable. We ve integrated a sophisticated 4-bearing main spindle arrangement to distribute axial and radial loads evenly. This design significantly extends the service life of the internal components, even when pushing the limits in hard rock formations. Spindle Diameter 90mm for maximum torsional rigidity. Flushing Hole of 25mm bore, optimized for high-pressure air circulation to ensure rapid cuttings removal.

Water Well Drilling: Perfect for both Tractor-mounted and Crawler-mounted rigs operating in tight residential or rural spaces.
Mining Operations: Rugged enough for Crawler-mounted blast hole or exploration drilling.
Multipurpose Utility: Easily adaptable for specialized geotechnical or construction piling projects.
