The Sealey SA501 is a pistol-type air needle scaler designed for removing heavy paint and rust scale from metal surfaces. This versatile surface preparation tool offers tradespeople an efficient solution for restoration work, fabrication projects, and industrial maintenance applications. Featuring a variable speed trigger control, this pneumatic scaler delivers up to 4500 blows per minute at 90psi operating pressure, allowing operators to adjust the intensity according to the surface condition and material being treated. The 43mm stroke provides effective coverage whilst the 4cfm air consumption makes it compatible with most workshop compressors equipped with a 1/4"BSP connection. The removable needle head configuration adds versatility to this tool, enabling conversion to a standard air hammer when fitted with an appropriate chisel set and spring retainer (available separately). This dual-purpose capability makes it particularly suitable for automotive restoration workshops, steel fabrication facilities, and maintenance operations where multiple surface preparation tasks are required. At 1.98kg, the tool offers a manageable weight for extended use whilst maintaining the robust construction necessary for demanding industrial applications.
