The JET 404203 flux chipper is a heavy‑duty, air‑powered chipping hammer delivering 4,500 blows per minute with a 1″ piston and 7/8″ stroke. Its compact 8.5″ body and lever‑throttle control give excellent control and access in tight spaces. Bit changes are quick thanks to a ball‑type chisel retainer. Ideal for removing scale, slag, welds or masonry, and can convert to a needle scaler for rust or paint removal.
