Center Drill Introduction
Center drill is a specialized drill bit used to create holes suitable for the center of a lathe. Its drill tip consists of two parts: one is the guide end, and the other is the larger countersunk hole end. It is typically used on lathes to drill precise holes required for the tailstock of workpieces. Carbide Twisted Center Drill Bit 6mm

Center drills are typically made of high-speed steel or carbide. Carbide center drills are widely used due to their durability and heat resistance. They are suitable for precise drilling on various materials. They can operate at high speeds, and compared to high-speed steel center drills, carbide center drills are more efficient in high-demand drilling tasks. Therefore, they are widely used in various industries, including the automotive industry, mold industry, and aerospace industry. Center Drilling Bit for High Precision Hole 2mm

Center Drill Usage Tips High Quality Hss Center Drill 5/ 3/ 2.5/ 2/ 1.5/ 1mm Bits
The performance of a center drill is influenced by its size and angle. Larger angles (e.g., 90°) are suitable for drilling harder materials, while smaller angles (e.g., 60°) are more suitable for drilling softer materials.

Using a center drill with an angle slightly greater than the main drill bit angle during machining can achieve optimal results.
Minimize drill bit deviation to ensure drilling accuracy.
Proper use and regular maintenance can extend the service life of the center drill.  3PCS 60° Center Drill Bit
