Twist Drill is widely used for drilling metal, wood, plastic and other materials.Its design and functionality make it an indispensable tool in various industrial fields. Here are the main advantages and features of twist drills:

Advantages of Twist Drills

Efficient cutting performance:

The spiral groove design of twist drill can effectively discharge drill cuttings, reduce friction ,avoid overheating, thereby improving drilling speed and work efficiency.

Wide working applicability:

Twist drill is suitable for processing a variety of materials, especially metal (such as steel, aluminum, stainless steel), wood, plastic and other materials, and has strong versatility.

High accuracy:

wist drills can provide high hole diameter accuracy and it's suitable for occasions that require fine machining, especially in scenarios that require accurate positioning and cleaning of holes.

Powerful cutting forces:

The double-edged design of the twist drill can provide even force distribution during cutting, thus improving the cutting force and ensuring a stable machining process.

Strong durability:

High-quality twist drills are manufactured with high hardness alloy steel or tungsten steel , which have strong wear and heat resistance ,it's are suitable for long-term high-intensity use.

Low cost and easy maintenance:

The cost of twist drill is relatively lower compared with other type of drill bits, the structure is simple, and the maintenance is convenient.

Features of Twist Drill

Double-edged design:

The typical design of twist drills is a double-edged construction that enables simultaneous feeding and cutting, ensuring a smoother and more efficient machining process.

Spiral groove design:

The spiral groove of the twist drill can effectively discharge chips, reduce the friction between the tool and the workpiece, and at the same time reduce the drill bit damage caused by overheating, maintaining the sharpness of the tool.

Drill Top angle (cutting angle):

Twist drills top angle have cutting angles 118 ° ， 135 ° and 140°and are suitable for machining most common materials.This angle provides good cutting performance and a long service life.

A wide variety of materials available:

High-speed steel (HSS), tungsten steel (Tungsten Carbide), cemented carbide and other materials can be used to manufacture twist drills to adapt to the processing needs of materials with different hardness and provide different wear resistance and thermal stability.

Coating:

The surface of twist drills is often coated to improve the durability and reduce wear, such as titanium coating (TiN),TiAiN or cobalt coating (Co), to improve their corrosion and wear resistance and prolong their service life.
