Powered by compressed air at 90 psi, it spins a 4 inch disc at up to 12,000 RPM and draws 39 CFM of air flow. The motor delivers 0.7 hp, making it well suited for aggressive sanding passes on metal, composites, and wood substrates. A rear exhaust location keeps debris and airflow directed away from the work surface. The 1\/4 inch inlet fitting connects to standard shop air lines. Metalworkers, fabricators, auto body technicians, and maintenance trades are the primary installers and operators of this tool.\u003c\/p\u003e\u003cp\u003eThe 54406 is designed for use with 4 inch abrasive discs in applications requiring controlled stock removal and surface finishing. The included 50192 Hard Density Locking-Type Backup Pad, 4 inch diameter, provides a firm foundation for consistent disc contact. Typical applications include weld seam blending, rust removal, paint stripping, and surface prep ahead of coating or inspection. This tool is intended for professional use in fabrication shops, manufacturing facilities, and field maintenance settings where a reliable air-powered sander is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 inch disc capacity with 12,000 RPM free speed for fast material removal\u003c\/li\u003e\n\u003cli\u003e0.7 hp air motor powered at 90 psi operating pressure\u003c\/li\u003e\n\u003cli\u003e39 CFM air consumption compatible with standard industrial compressor setups\u003c\/li\u003e\n\u003cli\u003eRear exhaust directs air and debris away from the operator and work surface\u003c\/li\u003e\n\u003cli\u003e1\/4 inch inlet for connection to standard shop air fittings\u003c\/li\u003e\n\u003cli\u003eIncludes 50192 Hard Density Locking-Type Backup Pad, 4 inch diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4 inch abrasive discs and includes the 50192 Hard Density Locking-Type Backup Pad measuring 4 inches (102 mm) in diameter.
