Drill Bit
In rotary drilling operations, the drill bits are the most critical terminal components for the drilling tool to achieve rock fragmentation and efficient cutting. They are essentially a high-hardness alloy cutter system installed around the drill bit, which precisely applies the rotary pressure and cutting force of the drilling rig to the rock surface, powerfully crushing and stripping the rock mass, while effectively protecting the drill bit body, ensuring that the drilling tool maintains stable cutting speed and operational life in high-intensity rock drilling construction.

The choice of alloy diameter depends on rock hardness and drilling rig type. Generally, 22-24mm for soft rock formations, 25-28mm for medium-hard rock formations, and 30mm+ for hard rock formations.
In conventional strata, the service life of tungsten carbide teeth is generally 300-800 hours, depending on geological conditions and operation methods.
Replace when the tooth wear exceeds 1/3 of the alloy diameter, or when cracking or detachment occurs, to avoid damaging the drill bit body.
