Top Hammer Drill Bits

Leading Top Hammer Drill Bits in China

     In Top Hammer Drilling the hammer produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit.

     Top hammer drill bits offer extended wear life, higher penetration rates, straighter holes and longer bit life.

What Are Top Hammer Drill Bits Used For?

    Top hammer drilling tools are commonly used for tasks such as drilling blast holes for explosives, creating anchor holes for support systems, and conducting exploration drilling. These tools utilize percussive action, where the drill bit strikes the rock surface at high frequency, enabling faster and deeper drilling.

How does the Top Hammer Drill Bits work?

    Top hammer drilling the method

    The working principle of the top hammer drilling system involves utilizing the compressed air pressure generated by the rock drill and the elastic force of the spring to transfer pressure through the drill rod. This pressure is then applied to the drill bit, propelling it to the rock surface.

Shank Adapters Features

    Threaded button bits use a proprietary grade of cemented carbide throughout and range from 28 – 152 mm in diameter. Various button shapes (spherical, semi-ballistic, and conical) and skirt designs (regular or retrac) deliver optimal performance in different rock formations.

    Key advantages of Top Hammer drilling include: Speed and Efficiency: Top Hammer drilling excels in surface drilling applications, offering higher drilling speeds and efficiency for shallower holes.
