The drill body is the primary structural component of a drill bit, which excludes the cutting edge and the shank. It serves to support the cutting section, transmit drilling force, and aid in chip removal while in operation.
Typically, the drill body incorporates various elements such as flutes for chip evacuation, margins for guidance, and a core for strength. Some designs also feature coolant channels to enhance drilling efficiency and tool longevity.
Common materials used for drill bodies include high-speed steel (HSS) , carbide , and coated alloys . The drill body plays a vital role in preserving stability, accuracy, and performance throughout the drilling processes.
Features:
Key Features
Spiral Flutes: Efficient chip removal and smooth drilling.
Strong Core: Ensures structural rigidity and reduces breakage.
