SCHMETZ 135X17 SD1/DPX17 SD1 SIZE 140/22 INDUSTRIAL SEWING MACHINE NEEDLES

Schmetz 135x17 SD1 Size 140 (NM 140 / Size 22) Industrial Sewing Machine Needles – Pack of 10

Sew leather, vinyl, and coated fabrics with precision using this pack of 10 Schmetz 135x17 SD1 industrial sewing machine needles, compatible with DPx17 SD1 systems. Designed for industrial lockstitch sewing machines, these chrome-coated needles deliver straight, clean seams with minimal material damage — perfect for heavy materials requiring professional stitch definition.

Needle Point – SD1 (Round Point with Small Triangular Tip)

The SD1 point combines the strength of a round point with a small triangular cutting edge. It cuts approximately 10% of the stitch hole, while 90% is displaced by the conical round point “R”. This unique geometry creates a straight, tidy seam with a smaller incision than standard cutting points — ideal for leather, coated fabrics, and synthetics.

Key Benefits:

• Designed for leather, vinyl, and coated materials

• Produces straight, even seams with minimal cutting

• Reduces material damage and ensures a neat finish
