Review on 🔧 Professional Rivet Nut Setter Kit - 16" Hand Rivet Nut Tool with 15 Metric & Inch Mandrels, 150 Rivet Nuts, and Sturdy Plastic Case by Paul Hyde

Do yourself a favor and get this version which includes the case with all the tool holders. As others have suggested, apply some light oil to the tool before first use. Another thought to keep in mind: if you're using excessive force when working with a tool, you're doing something wrong. The tool runs quietly and with constant force until the rivet nut is pressed in. If you continue to use force after tightening the nut, you can damage the tool.
