SMALL TRIANGULAR TIP "TRI/TIP" SERV7 REINFORCED

Schmetz 134 SD1 SERV 7 Industrial Sewing Machine Needles – SD1 Round Point with Small Triangular Tip – Enhanced Stability with Anti-Skip SERV 7 Technology

The Schmetz 134 SD1 SERV 7 needle is expertly engineered for precision sewing on fine leather, coated fabrics, and delicate synthetics. It features the SD1 point — a round point with a small triangular tip, offering a combination of piercing precision and fabric displacement. Unlike standard cutting needles, only 10% of the stitch hole is cut, with 90% displaced, ensuring a tidy, clean seam with reduced material damage.

What makes this needle even more powerful is its SERV 7 technology, developed by Schmetz to combat common issues like skipped stitches and needle bending. Thanks to a hump scarf and reinforced blade (up to +20%), the thread loop is optimally formed and more easily caught by the hook — even on stretchy or coated materials.
