Features
1.Center drill bits can be used to make conical holes for a lathe center in order to make a starting point for a standard twist drill, designed to prevent the twist drill from walking, as well as for producing center holds in components or work pieces with require machining between centers.
2.Available for all Kinds of Materials: Metal, Alloy, Copper, Iron, Wood, Aluminum, and so on.
3.Durable and Resistance: Center drill bit is made of HSS high speed steel, with extremely sharp blade, low consumption and durable with impact resistance, wear resistance. HSS Centre Drill Bits Set (1.6mm, 2mm, 2.5mm, 3.15mm, 4mm, 5mm)
4.center drills have flutes and cutting points on both ends. this allows the user with the ability to reverse the drill and utilize both ends.
5.Easy cutting with high speed and excellent offtake of chips.suitable for products with straight flute,oblique flute and spiral fiute,etc.
6.60 degree countersink angle fits all standard centers
7.High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance

Center drills are used to create a precise starting point, ensuring accuracy and preventing drill bit deviation. They are also used on lathes to drill precise holes in workpieces for tailstocks.

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.

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 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
