3) The characteristics of the product description
Features: Drill carbide teeth cone mosaic palm.
Major diameter: 4 5/8 ', 6', 7 ', 7 1/2', 8 1/2 ", 9 1/2", 9 5/8 ", 9 7/8", 12 1/4 ', 12 1/2', 3/4 14 ', 15', 15 1/2 ', 16', 17 1/2 ', 22', 26 and the like.
Tipped cone bit for medium, medium to hard, very hard strata, widely used in oil, mining, geological exploration, hydrological exploration, piling, geothermal development, well drilling and other fields.
My company can provide the actual drilling situation specific solutions, custom arbitrary diameter drill assembly, including large-caliber machine pile drill, different models drill, reaming drill bit, drill directional wells and the like.
1.1 Cutting Structure
Adopt a new formula of new technology of high-quality hard alloy tooth, enhance the cutting teeth mechanical properties.
1.2 gage structure
Using multiple gage protection structure: cone efflux insert trimming tooth (GT tooth), turn back; claw back set with carbide teeth; surfacing resistant Mo alloy; strengthen Zhao Jian and front side deposited weld; greatly improved
Drill gage capability.
1.3 bearing structure
Precision with radial sliding, two thrust bearings, ball tight. Tooth claw big journal and two stop surface welding have wear-resistant alloy, cone big hole and two stop surface solution inlaid special alloy and silver, increase
Vice plus bearing wear and anti-bite capacity, improve bearing ability of high speed vice adapt.
1.4 Seal lubrication
The use of advanced metal seal metal seal structure consists of two metal rings and two elastic rubber function circle composed of two functional metal ring on the cone ring and tooth claw metal ring on each functional ring
After the tension generated by the compression of the sealing surfaces of the two metal rings bonded together. Drill in the drilling process, the functions with respect to each tooth claw ring seal groove and the journal is always in the cone seal groove
Rest, play a static seal. Since the sealing reliability is greatly improved, greatly extending bit life, the metal seal for high speed drill bit. Limit the pressure
Type oil reservoir compensation structure to improve the reliability of the bearing lubrication. And grease are using imported special drill grease.
1.5 Products for
Metal seal bit stable performance, than the rubber seal bit longer life, suitable for underground power drill and high penetration rate turntable drilling.
