Hard layers slow down even the best equipment. But by pairing your Second-hand rotary drilling rig with optimized components, you can drill faster and with less tool wear.
1. SANY SR285RC + Conical Rock Bucket + Guide Ring
Rugged SANY used rotary drilling rig models like the SR285 perform better with conical buckets stabilized by guide rings to reduce bore deviation.
2. XCMG XR220D + Interlocking Kelly Bar + Rock Auger
This XCMG used rotary drilling rig cuts deeper using an interlocking kelly paired with a rock auger for torque stability.
3. SANY SR445 + Roller Cutter with Cooling Nozzle
This Reconditioned rotary drilling rig deploys a roller cutter integrated with fluid cooling, ideal for deep thermal rock zones.
Drill Faster With:
- Pre-aligned torque sensors
- Replaceable tip bits
- Fluid-cooled friction heads
XCMG used rotary drilling rig setups support preset drilling modes per geology type. SANY used rotary drilling rig users report up to 22% faster throughput with cooling-integrated heads.
