SCHMETZ 135X17 SD1/DPX17 SD1 SIZE 160/23 INDUSTRIAL SEWING MACHINE NEEDLES

Schmetz 135x17 SD1 Size 160 (NM 160 / Size 23) Industrial Sewing Machine Needles – Pack of 10

Sew heavy-duty leather, coated fabrics, and synthetic materials with precision using this pack of 10 Schmetz 135x17 SD1 industrial sewing machine needles, compatible with DPx17 SD1 systems. Built for industrial lockstitch sewing machines, these chrome-coated needles provide strong penetration, minimal material damage, and professional-quality stitch formation.

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

The SD1 (Round Point with Small Triangular Tip) design combines a round point with a fine triangular incision. Approximately 10% of the stitch hole is cut, while 90% is displaced by the conical round point “R”. This results in a straight, tidy seam with minimal fabric cutting — ideal for leather, vinyl, coated fabrics, and synthetics that demand accuracy and durability.

Key Benefits:

• Ideal for leather, synthetic, and coated materials

• Produces clean, straight seams with minimal cutting
