- High-quality Material : Made of high carbon steel and processed by centerless grinding. These drill bit have high precision, good shock resistance, and good toughness.
- Fine Cutting : This products adopts circular arc cutting, which has a small resistance to cutting and can effectively improve the speed of drilling. And its perforations are neat, smooth, and without broken edges, allowing you to use them to cut a fine and smooth circle surface.
- Fast Chip Discharge : This product adopts a bevel cutting-edge design. It reserves enough chip discharge outlets to make chip discharge easier. It can effectively improve your work efficiency.
- Precise and Stable : The middle teeth of the drill ensure precise and stable positioning during operation, and also effectively prevent shaking and sliding during operation. The X-shaped bit provides visibility and stability during operation. You can use it to create ideal circles and precise holes.
