Center Punch
A pointed punch used to mark a starting dimple so a drill bit does not wander.
What is it?
The center punch has a hardened, pointed tip that makes a small dimple in metal, giving a drill bit a stable starting point. It is essential for accurate hole placement.
What is it used for?
- Marking hole centers before drilling
- Starting drill bits on metal
- Marking parts for layout
How to choose
Choose a punch with a hardened, sharp tip and a comfortable knurled grip. A spring-loaded or automatic punch marks one-handedly.
Anatomy
Understanding the parts of a center punch helps you use, maintain, and buy it with confidence.
- Body: the main working portion of the tool
- Working end: the part that contacts the material
- Handle: the part you grip for control and leverage
Materials & construction
Quality center punchs are made from hardened, heat-treated steel (often chrome-vanadium or high-carbon) chosen for strength, edge retention, and resistance to wear and corrosion.
Safety & maintenance
- Wear safety glasses; metal chips and fragments are sharp
- Use the correct technique and pressure for the material
- Keep the tool clean and store it safely
- Fit a handle where the tool uses one to protect your hand
