What are the characteristics of different types of carbide drill bits?

Solid carbide drill: It has a centering function, a relatively complete range, and can correspond to deep hole processing. The processing accuracy is high, and the regrind is reused, which effectively reduces the processing cost.

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

Replaceable cutter head type cemented carbide drill bit: with centering function, complete variety, the same tool holder 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.
