The ball-tooth drill bit is a rock drilling tool widely used in mining, geological exploration, water conservancy projects and stonework projects. Its main structure includes drill bit body, ball teeth and washers. The drill bit body is the supporting part of the ball-tooth drill bit. It is usually made of materials such as carbide and can withstand high-intensity impact and wear. Buttons are many small balls covered on the drill bit. Their hardness is higher than the rock or ore to be drilled, and they can break the rock and ore. The washer is located between the ball teeth and the drill bit body, which can prevent excessive wear of the drill bit, protect the ball teeth and drill bit body, and improve the integrity of the drill bit.
The working principle of the ball tooth drill bit is: when the drill bit rotates, the ball teeth contact the rock or ore, forming an intermittent impact load, thereby driving the drill bit downward into the formation. The ball teeth are arranged in different ways and can be adapted to different types of rocks and ores. For example, a sparse tooth arrangement is used in highly abrasive rocks to improve drilling efficiency; a dense tooth arrangement is used in soft rock and clay to increase the cutting amount. .
The advantages of ball tooth drill bits include high drilling speed, high footage, low energy consumption, low noise, long life, etc., and can adapt to different lithology and formation conditions. During operation, you need to pay attention to safety and operating regulations to avoid accidents caused by using incorrect specifications and types.
