Roller cone rock reamer:
"KING DRILLING" can provide 220-1600mm HDD rock reamer with roller cones. The roller cone reamer fit for all sorts of rock formation.
The cone bearing is designed with metal seal or o-ring seal.IADC114-737 tooth type available for different formation.
1. According to the drilling machine characteristic and different formation conditions, choose appropriate tooth shape and bearing structure.
2.Cold mounting Wear resistant alloy,Reduce the wear and tear.
3. Unique cone to prevent fall off technology, prevent damage of bearing roller falls within the hole cause an accident.
4. Hydraulic rock breaking, Slag discharge smoothly, reduce slag accumulation.
5. The welding craft guaranteed that, prevents the welding superheat.
6. The guide spiral belt design of bit body, Guide and slag guiding effect is good, Reduce duplication broken.
Roller cutter rock reamer:
1.Rock reamer with replaceable roller cutter is suitable for big rig drilling large diameter heavy loads crossing project and all kinds of rock formations,400-2000mm hole opener are available.
2.The broken rock cutting tool uses the large diameter metal seal roller cutters,the main Body can be used repeatedly,Change the cutter convenient.roller cutters divided into three types , can be adjusted to achieve different reaming diameters.
3.All roller cutters bearing are metal sealed,also Large diameter cutters, long bearing life, generally work over 100 hours.
4.Unique multi-level anti-off interlock device,prevents cutter thread off when the reamer idle operation and The cutter outer covering falls off when the bearing damage.
5.Excellent hydraulic design,fully considering the slag discharging unobstructed,simultaneously realizes the water power broken rock.
6.The reamer body made of high quality alloy steel forging,good solderability,convenient scene patching.
7.The guide spiral belt design of reamer body, Guide and slag guiding effect is good, Reduce duplication broken.
8.For large reamer body,using the weight reduction design,effectively reduce the tendency of the pipe line trajectory change,reduce the resistance when reaming hole and pulling pipe.
