product manual:

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.
