SCHMETZ 1738 D — industrial sewing machine needles for leather

1738 D, 16x230 TRI are SCHMETZ industrial sewing machine needles with a triangular cutting point, designed for sewing hard, dry leather. The D-type point penetrates dense materials more easily and helps create a straight, precise seam.

D cutting point features

D (Triangular Point) is a triangular cutting point with a pronounced cutting action. It creates a triangular incision and helps maintain the needle’s direction when sewing stiff materials. Visible holes may remain at the stitch points, so it is important to choose a suitable needle size and stitch length.
