Overview
Not a hole-making punch, this Klein bull pin is a forged, heat-treated steel pin with a broad angled head and a black finish. The material is alloy steel, with a brushed finish listed alongside the black coating.
A forged, heat-treated body is what a bull pin needs, since the head takes hard blows. The listing is light on use cases and gives a single piece in the box. The warranty is a year from the manufacturer.
Who it's for
Someone who needs a heavy bull pin for aligning and driving gets forged, heat-treated steel in a single piece. Shoppers looking for small pin punches or a set should look elsewhere, as this is one large pin.
Pros and cons
- Forged, heat-treated steel
- Broad angled head takes blows
- Manufacturer warranty included
- Single pin, not a set
- Use cases not described
- Finish listed as both black and brushed
- Warranty limited to one year
Performance notes
Forging and heat treating decide how the pin holds up to hard strikes, and the broad head spreads the blow so the end mushrooms less. The tapered or straight shank profile is not described. Diameter limits what holes it can enter.
