The DOT Die Set Hand Tool 22-RHT1RR is a manual metal grommet hand tool designed specifically for installing size #1 rolled rim grommets and spur washers. This hand tool kit includes a hole cutter, inserting die, die block, and plastic base, making it suitable for use on materials like canvas, leather, tarps, boat covers, awnings, and various industrial fabrics. It requires a pre-punched hole and manual pressure, often with a mallet or hand press, to create strong, durable, and long-lasting grommet settings. Rolled rim grommets offer a smooth edge, while spur washers feature interlocking teeth to securely grip the fabric, making this tool ideal for DIY repairs and small production runs where precision and durability matter.
