Question: 1 / 400

What is the included angle of a standard center punch?

30 degrees

45 degrees

60 degrees

The included angle of a standard center punch is typically set at 60 degrees. This angle is designed to create a conical point that is effective for indenting surfaces to guide a drill bit accurately. The 60-degree point ensures that when the punch strikes the material, it produces a small, precise indentation that minimizes slipping and helps align the drill bit, which is critical for achieving accuracy in machining and metalworking tasks.

Selecting a center punch with a 60-degree included angle strikes a balance that is widely accepted in the industry, making it the standard for various applications where precise marking and drilling are required.
