Description

Product Description:

The drill body is the main structural part of a drill bit, excluding the cutting edge and the shank. It supports the cutting section, transmits drilling force, and assists in chip removal during operation.

Typically, it includes features such as flutes for chip evacuation, margins for guidance, and a core for strength. In some designs, it also contains coolant channels to improve drilling efficiency and tool life.

Common materials include high-speed steel (HSS), carbide, and coated alloys. The drill body plays a crucial role in maintaining stability, accuracy, and performance during drilling processes.
