The drill body serves as the primary structural component of a drill bit, with the exception of the cutting edge and shank. It serves various functions such as supporting the cutting portion, transmitting drilling force, and aiding in chip removal while in operation.
Typically, the drill body incorporates elements like flutes for chip evacuation, margins for guidance, and a core for added strength. Some designs may also feature coolant channels to enhance drilling efficiency and extend tool life.
Commonly used materials for the drill body include high-speed steel (HSS), carbide, and coated alloys. It plays a critical role in ensuring stability, precision, and overall performance throughout drilling operations.
Features:
