Drop segment

Hello everyone!!

I cannot figure what "drop segment" means in this sentence... Can anyone help me, please?? It comes from the explanation of a core drill...

Thanks in advance!!!

"Unique front drop segment design allows for greater support and protection when entering into material, increasing the quality and life of the tool."

Core drill bits have two protective cylindrical shells.

Crenellated protective shells help to spin off bore material through the open segments of the sides thereby diminishing the probability of the drill bit getting clogged.

Hello!!!

Sorry for my late response!!! And thank you very much for you help!!!

The translation for "drop segment", according to some research and help from many colleagues is "segmento de extracción frontal".

Thanks!!!!!!!
