What degree drill bit is best for metal?

In the modern manufacturing and processing industry, the geometric angle of the drill bit directly affects the drilling efficiency, hole position accuracy, and tool lifespan. Different "drill bit angles" (typically referring to the tip angle / clamping angle) are suitable for different materials and working conditions. Choosing the appropriate drill bit angle is the key to ensuring production efficiency and processing quality.

Today, Hiboo Tools will provide you with a comprehensive analysis of the various types, features and applicable materials of common drill bits, helping customers make scientific selections and improving processing efficiency.

What is the drill bit angle?

The drill bit angle usually refers to the apex angle formed by the cutting edge of the drill bit (Point Angle), which is the angle between the two main cutting edges of the drill bit. This angle affects the entry cutting method, force application method, and drilling performance when the drill bit contacts the surface of the workpiece.

Common types of drill bit angles and their application scenarios

How to choose the correct drill bit angle?

Processing soft metals? Choose 118°: such as aluminum and brass, it can quickly penetrate and reduce the risk of the tool getting stuck.

When drilling stainless steel or hard alloy steel, choose a drill bit with an angle of 135° or more to prevent slipping.

High-precision or high-speed CNC drilling? Special drill bits with an angle of over 140° are available.

High alignment accuracy? Choose the Split Point design, which comes with a self-centering effect.
