Overview
The ST475AIR is an all steel chisel measuring 4 by 7.5 inches, with both blade and handle built from alloy steel. The AIR designation in the model name suggests pneumatic use, though the spec sheet lists no power source to confirm it.
An all metal construction, blade and handle alike in alloy steel, points to a tool built for striking rather than one with a wood or composite grip. The model name including AIR hints this may be designed for use with an air hammer, but that detail is not confirmed in the listed specs.
- Alloy steel blade and handle
- 4 by 7.5 inch size
- Model name suggests pneumatic use
- Rated 4.7 stars across 118 reviews
Who it's for
Could suit someone running a pneumatic air hammer who needs a compatible bit sized at 4 by 7.5 inches. Anyone needing confirmation of the power source or shank fitment should check the full listing first, since neither is given here.
