Overview
Pin punches drive out spring bars, lever pins and small rivets when leverage alone is wrong. Matching diameter to the pin protects shoulders and holes. A punch that is too small mushrooms the pin; one that is too large bruises the lug.
Use a proper block or support so force goes through the pin, not into twisting the case. Guide the punch square. Angled hits are how you invent new scratches.
Keep a few lengths and tips. One lonely punch tempts misuse.
What matters about it
- Diameter match is non-negotiable
- Support the work or you bend what you meant to free
- Square strikes prevent walking marks
- Dedicated tips for soft pins versus hardened pins
- Control matters more than hammer enthusiasm
Practical notes
- Start with light taps to confirm alignment.
- Catch spring bars as they exit — they travel.
- Do not use a punch as a screwdriver or pry bar.
- Dress mushroomed tips before they slip off pins.
