To OP. There is no such thing.
I used mine to customize into other purpose hammers. Do not assume you can shrink with it.
A shrinking disc is an item that actually works.
Yes, a shrinking hammer does work but you need to use it with the shrinking dolly, neither will work by themselves but they mar up the surface too much to be of much use for metal working, good enough for a body man just prepping for a coat of bondo. I highly doubt a HF set will work much better than a rock tied on a stick though. The shrinking disc does work best with the most control over the work with the least amount of damage to the surface. Another place to get some good hammers is from aircraft tool supply (ATS). Nicely machined and made for metal working. Not something you would ever hit a chisel with without a second thought
