Industrial sewing machine needles SCHMETZ DBx1 (1738) SD1 for leather - 10 pcs.

SCHMETZ DBx1 SD1 industrial needles are designed for lockstitch sewing machines when sewing leather and other "difficult" materials. SD1 or "Round point with small triangular tip" is a special fine triangular cutting point that makes a smaller incision than typical cutting needles and ensures a straight, neat stitch even in multi-directional sewing (programmable sewing machines).

🧵 Most Suitable Materials

• Fine leather and leather imitation
• Thin synthetic "leather" materials
• Coated materials with PVC/PUR (tarpaulins, tents, coated tablecloths)

Result and Advantages

• Precise stitch appearance and less needle deviation compared to a standard round point (R) needle
