R32 Tungsten Carbide Domed Fast Drilling And Quarrying Tools Thread Reaming Button Bit

Reaming drilling tools are used when a large diameter is needed to be reamed out after a pilot holes is drilled to a depth. We manufacture pilot reaming drilling tools, domed reaming button bits and adapter reaming button bits. Pilot reaming bits consist of pilot adapters and reaming bits, both domed bits and adapter reaming bits are integral. Dome bit is usually used when the pilot bit needs to enlarge the hole diameter after drilling to the specified depth.
Thread: R25, R28, R32, R38, T38, T45, T51
Pilot adapter diameter: 26mm ~ 40 mm.
Reaming button bit diameter: 64mm ~ 152mm.

1. High-strength, high flexibility, high temperature, high wear resistance.
2. High-precision metal seal.
3. Locking roller ball, to adapt to high-speed.
4. Use high strength high toughness carbide teeth
5. Hours in the rotary cone bit with the impact, crushing and shearing the role of broken rock.
6. Cone bit to adapt to the soft, medium and hard of various strata.
7. Reasonable price and long working life.
