SCHMETZ 1738 SD1 — industrial sewing machine needles for fine leather

1738 SD1, 16x231 SD1 are SCHMETZ industrial sewing machine needles with a special SD1 point design for fine leather, faux leather, and various coated materials. This point type helps create a precise, straight seam with less material cutting than pronounced cutting points.

SD1 cutting point features

SD1 (Round Point with Small Triangular Tip) is a round needle point with a small triangular cutter. It combines the principles of cutting and displacing the material.

The small triangular tip cuts approximately 10% of the stitch hole, while the rest is opened by displacing the material. This design helps reduce material damage and create a neat, straight seam.

• Leather garments and fine leather goods.
• Thin faux leather and synthetic leather materials.
• Fabrics and technical materials with PVC or PUR coatings.
• Thin plastic films and coated materials.
