Industrial Duty Air Needle Scaler; 9/16" Stroke with 5500 Blows Per Minute

Inline needle scalers align their needle-holding barrel with the tool grip to form a slim, straight tool for reaching through openings and into recesses or tight spaces. Their lever switch activates the tool to strike the needles against surfaces to remove rust, mill scale, and paint. The needles are loosely bundled rods that move independently to follow curves and contours. They can be changed out for a different needle diameter or material as long as the needles are compatible with the scaler. Needles can be replaced when they break or wear out.
