Customized Modular Replaceable Tip Bits DC 12.5-42mm High Accuracy

The drill body is an essential component of a drill bit , which is responsible for providing structural support and transmitting forces during drilling operations. It is distinct from the cutting edge and the shank. The primary functions of the drill body include supporting the cutting portion, facilitating chip removal, and ensuring the efficiency of the drilling process.

Key features of the drill body include flutes for chip evacuation, margins for guidance, and a core for enhanced strength. Additionally, some designs may incorporate coolant channels to improve the overall drilling efficiency and extend the tool's lifespan.

Various materials are commonly used in constructing drill bodies , such as high-speed steel (HSS), carbide, and coated alloys. The selection of the appropriate material is crucial for maintaining stability, precision, and optimum performance throughout the drilling process.

Features:

- Spiral Flutes: Efficient chip removal and smooth drilling.
- Strong Core: Ensures structural rigidity and reduces breakage.
- Precision Margins: Improve hole accuracy and reduce vibration.
- Optional Coolant Channels: Enhance heat dissipation in high-speed drilling.
