ACUTE ROUND POINT "SPI"

Schmetz 2091 / 175X7 / TQX7 SPI Industrial Sewing Machine Needles – Acute Round Point 

These Schmetz 2091 / 175X7 SPI industrial sewing machine needles are precision-engineered with an SPI (Acute Round Point), allowing them to pierce densely woven or coated materials with accuracy and minimal disruption.

The SPI point is extremely slim, making it ideal for producing clean, accurate seams on lightweight fabrics such as silk, microfabrics, coated textiles, and taffeta. These needles are also suitable for fur garment construction and fine shirt stitching like collars and cuffs, offering a smooth stitch appearance with reduced puckering.

The chrome coating ensures smooth needle movement, reduced wear, and improved stitch consistency in high-speed industrial applications.
