Drill bit angles refer to the included angle between the drill bit's cutting edges. Different angles are suitable for different materials and machining methods.
118-degree angle: Suitable for ordinary drilling of hard materials such as steel and iron.
135-degree angle: Suitable for softer materials such as cast iron, copper, and aluminum, reducing torque and impact during start-up.
90-degree angle: Suitable for non-metallic materials such as wood and plastics.
In addition to these commonly used angles, there are also drill bits with special angles, such as 60-degree and 75-degree angles. These angles are typically used in specific industries or machining methods, such as aerospace and automotive manufacturing.
