Q: Does the 31964 fit standard air hammers?
A: Yes. The .401 inch parker turn-type shank is universally compatible with most pneumatic air hammer systems commonly found in automotive and industrial repair.

Q: Why use a concave striking surface?
A: The 1 inch concave surface focuses the impact into a tighter area, reducing slippage and increasing precision on tasks like frozen bolt removal or dent reshaping.

Q: Does the black oxide coating offer real benefits?
A: Yes. It enhances corrosion resistance and extends bit life when exposed to moisture or solvents in workshop and under-vehicle environments.
