Drill Bit

FMRIBT uses imported high-quality alloy steel and the best cemented carbide made in China to produce all thread ball tooth drill bits through hot pressing technology.

Thread size: R25, R28, SSR28, R32, SSR32, R35, SSR35, R38, T38, T45, T51, SST58, SST68, SGT60

Head diameters: 33mm ~ 152mm;

Face designs; flat face,convex face,convave face,convex-convace face,double gauge face,drop-center face

Alloy buttons are hot mounted into the drill bit, ensuring the bit good accuracy and durability

Reliability ensured by premium drill bit materials and premium alloy button

Different types designed for different drilling scenarios and rock conditions

Cost-effective, good performance with reasonable price.

Customers can choose their own brand logo on the packaging and bit color to show their unique image.

Shank Adapter

Shank adapter is designed to transmit power from rock drill piston to extension drill rod and finally to drill bit. When deploying, one side of shank adapter is connected to drill rod, while the other side should be connected with coupling or extension drill. Shank adapter can be deployed for drilling duties in tunneling, construction, mining, quarrying, etc.

Thread type: R25, R28, R32, R35, R38, T38, T45, T51, etc

Diameter: 32mm-70mm

Length: 273mm-885mm

Precision and reliability granted by premium material, fine CNC machining and heat treatment processes

Carburizing process is applied to promote surface hardness, ensuring better wearing quality

Correction value: The drill bits we produce will be tested by our data inspectors

Drill Rod

Hexagonal drill rod are produced by CNC machining and advanced heat treatment.(Hexagonal Drill Rods,Round Extension Drill Rods,Fully carburized taper drill rods,Integral Drill Rods,Tapered Drill Rods)

Thread size: R22, R25, R28, SSR28, R32, SSR32, R35, SSR35, R38, T38, other.

Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;

Cost-effective, good performance with reasonable price.

Complete types of drill rod for various drilling scenarios.

Coupling

Coupling is used for connecting shank adapter and extension drill rod together, or for connecting two extension rods together. Besides normal equal couplings, we also offer reducing couplings that are able for changing thread type and size.

Thread type: R25, R28, R32, R38, T38, T45, T51

Diameter: 35mm, 40mm, 45mm, 55mm, 63mm, 66mm, 72mm, 76mm

Length: 150mm, 155mm, 170mm, 180mm , 180mm, 190mm, 210mm , 235mm

Coupling type: Semi-bridge, Full bridge, Adapter Coupling

Premium steel as material, precision CNC for manufacturing, accuracy and reliability assured;

High transmission efficiency grants high drilling efficiency for the drilling system.
