The “artifact” used to grind rocks when mining and tunneling, carbide spherical drill bit

Carbide drill bit is a kind of equipment used in drilling engineering. It breaks rocks by the impact load generated by the drilling pressure and its own rotation. During rock drilling, the drill bit is subjected to high-frequency impact loads and is subjected to various composite stresses such as torsion, bending, tension, and compression. It …

carbide drill bits, choose carbide drill bits

What factors need to be considered when choosing carbide drill bits?

1. Processing accuracy   When choosing a carbide drill bit, you first need to consider the dimensional accuracy requirements for drill bit processing. Generally speaking, the smaller the hole diameter, the smaller the tolerance. Therefore, drill bit manufacturers often classify drill bits according to the nominal diameter size of the hole being machined. Among the …
