The included spare springs, not just spare tips, make this the more repairable option in this category if the spring is what tends to fail on cheaper punches.

Overview
Mulwark's 5 inch automatic center punch set ships two punches in a storage case, each with a palm cap, a replacement tip and an extra spring, so the whole spring assembly can be rebuilt rather than just the point swapped.
Where most punches in this category only include a spare tip, Mulwark also boxes in spare springs, which addresses the specific failure mode other budget punches in this same category are reported to have. The orange adjustable cap sets strike force, and the pair comes in a dedicated case rather than loose packaging.
- 5 inch Cr-V steel punch pair
- Storage case included
- Spare tips and spare springs
- Adjustable orange tension cap
Who it's for
Buyers who have had a spring loaded punch wear out before and want spare internal parts on hand, or anyone who wants the set stored in a case rather than a bag.
Pros and cons
- Includes spare springs as well as spare tips
- Comes with a dedicated storage case
- Cr-V hardened steel construction
- Adjustable orange cap for strike force
Performance notes
Cr-V steel construction and the orange adjustable cap set how much force the internal spring delivers when the punch trips, aiming for a consistent dimple size strike after strike. Because Mulwark includes extra springs alongside extra tips, a worn spring can be replaced instead of retiring the whole punch.
