Solid carbide drill: It has a centering function, a relatively complete variety, and can correspond to deep hole processing, with high processing accuracy, regrinding and reuse, and effectively reducing processing costs.

Carbide indexable insert drill: Disposable inserts, low cost, convenient tool change, usually 2D-6D specifications, no centering function, rich insert types, a wide range of correspondence, and relatively low machining accuracy.

Replaceable cutter head type cemented carbide drill bit: with centering function, complete variety, the same cutter shaft can be installed with various diameter cutter heads, high processing efficiency, high processing accuracy, and various materials of cutter heads can correspond to different materials , Re-grinding the cutter head can further reduce the cost.
