ROUND POINT WITH SMALL TRIANGULAR TIP "SD1"

Schmetz 251 SD1 Industrial Sewing Machine Needles – Chrome Coated – Round Point with Small Triangular Tip (TRI TIP) 

The Schmetz 251 SD1 needles, also known as TRI TIP needles, are engineered for exceptional seam quality when working with fine leather, synthetic leather, and coated materials. Featuring a round point with a small triangular incision, these needles cut approximately 10% of the stitch hole, while displacing the remaining 90% — delivering straight, clean seams without damaging delicate materials.

Perfectly suited for multi-directional programmable sewing machines, these needles maintain consistent stitch appearance regardless of sewing direction. The chrome coating enhances durability and ensures smoother penetration, even through tough synthetic or laminated layers.
