Product description
RC drilling refers to Dual Wall or Dual Tube Drilling. RC drilling
applies two rods with inner and outer tubes. Air is blew down the
annulus of the rod and enter into hammer and bit. Rock formation
fragments crushed by bit are collected into the inter tube via air
hole on the bit head. And then returned to the ground and enter
into sampling system. RC hammer is our most advanced products,
mainly used in deep hole exploration drilling and mining ore grade
control.

Features
Using higher grade carbides for longer life;
Minimizes hole erosion in fragile formations
Drills faster through soft formations with less blockages
Drills straighter through consolidated and unconsolidated
formations
Characteristics
- Reference the design and production experience of conventional
DTH hammer and combine the operating characteristics of RC hammer;
internal structure design is optimized to ensure ideal energy
transfer and high drilling speed as well as steady sampling.
- Simple internal structure and rigid components ensure long using
life and easy maintenance of the hammer.
- Sample tube is integrative designed and can be placed without
disassembling of the hammer. With carburizing treatment, the sample
tube has good wear resistance.
- RC bit has patented design. One hammer could drill different size
of holes just by replacing different size bits, and ensure no
contamination of the sample as well.
- In difficult conditions such as loose soil, hard rock formation
or plenty of water exists, sampling can be done well.
Applications
At present, DTH RC drilling tool is widely used in underground
mining, quarries, hydraulic and Hydro-Power Engineering, water well
drilling, Mineral exploration, anchoring hole drilling, geothermal
engineering, Subway excavation, another civil engineering.
