The Schmetz 134 DI Size 125 industrial sewing needles are equipped with a DI diamond cutting point, which forms a rhombic incision in the seam direction. Thanks to its four sharp cutting edges, the DI point penetrates dense and hard materials more easily, resulting in a straight, recessed seam that is durable and precise. With a chrome coating to enhance durability, these needles are perfectly suited for industrial lockstitch sewing on heavy-duty materials.
