What the AI looks for in Center Punches
- Point angle
- Center punches are typically 90 degrees and prick punches are about 60 degrees. A 90 degree mark guides a drill, while a 60 degree prick mark is for fine layout.
- Adjustable force
- On an automatic punch, the cap should adjust impact force. Soft metals need light marks and steel needs deeper ones.
- Replaceable tip
- Prefer automatic punches with replaceable points. Tips wear, and a replaceable tip saves replacing the whole tool.
Brands that matter
- Starrett: Benchmark automatic center punches.
- General Tools: Budget automatic and struck punches.
- Mayhew: Durable struck center punches.
What to avoid
- Using a center punch on hardened steel
- Glass-breaking automatic punches sold as layout tools
