FWIW, since you're looking at China tools anyhow, my HF air hammer has been just fine the 6-8 times I've used it. As a hobbyist the opportunity to use one only pops up every so often.

Not sure what is included with that "kit" but mine came with 5 bits and the "pointy" one is plenty to start a stubborn pin, then just finish up with a regular punch and hammer.

Thes are NOT pro quality tools but they're not made of total peanut butter either.
