SCHMETZ DPx17 SD1, 135x17 SD1 industrial sewing machine needles for leather, 10 pcs

DPx17 SD1, 135x17 SD1 are SCHMETZ industrial sewing machine needles with an SD1 point, designed for sewing leather, artificial leather, and coated materials. The special point design combines a slight cutting action with material displacement, helping to create a straight, even seam.

SD1 needle point features

SD1 (Round Point with Small Triangular Tip) is a round point with a small triangular cutter. It cuts approximately 10% of the stitch hole, while the remaining 90% is opened by displacing the material with the conical round point.

Compared with pronounced leather cutting points, SD1 makes a smaller cut. This helps create a neat, straight seam and reduce the risk of needle deflection. SD1 is also suitable for multidirectional sewing, as the stitches remain consistent in appearance in different sewing directions.

• Artificial leather and thin synthetic leather materials.
• Materials with a PVC or PUR coating.

Compatibility and needle selection

These needles are designed for industrial sewing machines whose technical documentation specifies the DPx17 SD1 or 135x17 SD1 system. Before purchasing, check the needle system and choose an NM size suitable for the material and sewing thread.

Important: SD1 is not a universal round point. Its slight cutting action is not suitable for all textiles. For knitwear, SES or SUK point types should generally be considered. Test the results on a sample of the specific material before sewing.
