Vacuum Brazed diamond drill bit for hard rock

Product Name:Vacuum Brazed diamond drill bit for hard rock

Item no:Vacuum Brazed diamond drill bit for hard rock

Features and Benefits

1.Excellent drilling speed,drilling life,adaptability to various coring work in complex rock.

2.Low drilling resistance, excellent power for ultra hard rock and controling the change of diameter size.

3.High cost-performance

4.By two-way vacuum hot-pressing automated production technology, make a bit out of the blade more reasonable and scientific.

5.The world's top abrasive, ensure the quality of the drill bit.

6.Break through the traditional thinking by adopting the technology of extrusion single crystal gauge, abandon the polycrystalline adopts monocrystal gauge inside and outside, let the drill head breathed sighs of relief, drilling rapidly.

7.Top abrasive combined with special low lip surface structure, drilling the  rock drill efficiently.

Technological advantage

1) Advanced equipment. 

The unique system of large automatic self-heating vacuum hot-pressing sintering (HPS) which we initiated,is not only easy to operate and simple in molding technique,but also has an obvious advantage of high efficiency and precision.  

2) Advanced composite die

We took the lead in introducing high strength composite die in manufacturing cemented carbide products,which improved the product quality greatly.

3) Technical maturity

Exclusive technology of charging and vacuum blending,ensures the product purity and no harmful gas casued.

4) Unique technique

Our new technique has excellent performance of high efficiency, energy saving and environmental protection,
