Products Description
Rotary drilling is mostly used to drill big holes in large quarries, open pit mines, petroleum extraction, and other fields:
1.rotary crushing by high-point loading to the rock from three cones.
2.rotary cutting by shear force from drag bits. The rotary cutting can be also used to drill small boreholes in soft rocks.
For example, rotary drilling is often used to drill small holes down to 25 mm in diameter to install bolts in coal mines. The rotary crushing is used in medium to hard rocks, and the rotary cutting in soft rocks.
HKX435-311 increasing efficiency, and reducing costs. This product allows for faster drilling, creating fewer delays and allowing for more productive work schedules.
HKX435-311 can help drill deeper and more accurately than ever before. These bits use three rotating cones, each with its own set of teeth, to grind away rock and other materials in a way that's highly precise and efficient.
As a result, mining companies can extract more valuable resources more quickly, while also minimizing the environmental impact of their operations. HKX435-311 bits also reduces the need for manual labor, which reduces the potential for accidents and injury.
