Product Description:
The drill body is the principal structural component of a drill bit, apart from the cutting edge and the shank. Its primary functions are to provide support for the cutting portion, transmit the drilling force, and aid in ejecting chips while in operation.
Typically, the drill body possesses various elements such as flutes to facilitate chip removal, margins for direction, and a core for reinforcement. Depending on the design, it may also include coolant channels to enhance drilling efficiency and prolong tool life.
Materials commonly used for drill bodies comprise high-speed steel (HSS), carbide, and coated alloys. The drill body plays a pivotal role in ensuring stability, precision, and effectiveness throughout the drilling procedures.
