Product Description:
The drill body serves as the primary structural component of a drill bit, encompassing everything except for the cutting edge and the shank. Its functions encompass supporting the cutting portion, transmitting the drilling force, and aiding in the removal of chips when operating.
Key elements of a drill body typically include flutes for facilitating chip evacuation, margins for providing guidance, and a core for enhancing strength. Some designs may also incorporate coolant channels to boost drilling efficiency and prolong tool life.
Materials commonly used for creating drill bodies include high-speed steel (HSS), carbide, and coated alloys. The drill body plays a pivotal role in upholding stability, precision, and overall performance throughout the drilling procedures.
