This ball tooth is a core drilling component specially designed for the "precise hole diameter" demand scenario. Its core advantages focus on "high consistency of 110mm hole diameter + low disturbance on the hole wall + durability of medium soft rock", precisely adapting to scenarios with strict requirements for hole diameter accuracy such as tunnel anchor bolt holes and mining equipment installation holes, ensuring the accuracy of subsequent construction from the source.

Its key performance is optimized around the dual dimensions of "precision" and "stability" : First, the shape and arrangement of the ball teeth have been precisely designed, causing minimal disturbance to the hole wall during the drilling process. This can strictly control the deviation of the hole diameter, ensuring that the height of the hole diameter within the 110mm specification is consistent. This provides a suitable foundation for the subsequent precise implantation of anchor rods and the installation of mining equipment, avoiding installation rework caused by hole diameter deviation. Second, it adopts high-wear-resistant alloy materials, which can operate continuously for a long time in medium-soft rock layers such as marble and limestone. It is less likely to suffer from tooth wear due to rock layer friction, ensuring the stability of the drilling process and reducing the impact of frequent tooth replacement on the accuracy of the hole diameter.

In practical applications, it can directly enhance the construction efficiency of tunnel support and mining equipment installation - it can meet the precise assembly requirements of anchor rods and equipment without secondary hole repair, and at the same time, it reduces the frequency of shutdown maintenance due to its anti-wear durability. It is the preferred drilling component in scenarios where "hole diameter accuracy" is pursued in the tunnel and mining fields.
