Button drill bit are used with hydraulic rock drills for fast perforation and to save drilling assistance hours in order to increase the industrial drilling speed. The trend of development started with the ball tooth tooth tooth bit for deep well drilling in oil wells and the ball tooth drill bit for deep hole drilling in mines. Gradually developed to a wide variety of rock drilling with large, medium and small diameter ball tooth type series of bits. The way of fixing the teeth is by welding, cold pressing and hot embedding. Column tooth convex bit in the drilling process has its own role in the repair and grinding, so the drilling speed is higher, while the concave bit drilling, the bottom of the hole part of the rock to maintain a section of the convex, have the role of the guide direction of the correct drilling. Column tooth coring bit: five sets of ball teeth are set on the lip of the bit, the lip is conical inside, five evenly distributed ball teeth are set on the inner cone, and there are five rectangular injection holes on the lip to inject compressed air into the bottom of the hole in order to cool the bit and clean the bottom of the hole.

A button drill bit is a type of rock drilling tool commonly used in mining, construction, and geotechnical engineering applications. It is designed to penetrate and break up rock formations during drilling operations.

Button drill bits are characterized by the presence of hardened steel or cemented carbide buttons on the bit's face. These buttons are typically spherical or hemispherical in shape and are strategically placed to provide impact and cutting action against the rock.

The buttons are made from hard and wear-resistant materials, such as tungsten carbide or diamond inserts. This helps to ensure durability and longevity, as well as efficient rock penetration.

Button drill bits come in various configurations, depending on the specific drilling requirements. There are different button arrangements, button sizes, and bit body designs available to suit various rock types, drilling methods, and drilling machine capabilities.

The drilling force and rotation provided by a drilling machine or rock drill transfer energy to the buttons on the bit's face, allowing them to penetrate the rock and break it apart. The button arrangement and spacing on the bit's face help distribute the drilling force evenly for effective rock breaking.

Proper maintenance and regular inspection of button drill bits are important to ensure their optimum performance. This includes monitoring the wear of the buttons and replacing worn or damaged buttons as needed. Some button drill bits also have replaceable bit bodies, which can be replaced when they become worn or damaged.

In summary, a button drill bit is a specialized rock drilling tool featuring hardened buttons on its face for efficient rock penetration and breaking during drilling operations. These bits are used in diverse industries, such as mining, construction, and geotechnical engineering. The configuration of the buttons and bit body can be tailored to specific drilling requirements, ensuring effective rock breaking.
