REVERSE TWIST POINT "LR" OR "R TW"

Groz Beckert 34 (R TW) / 287 / 16x1 Industrial Sewing Machine Needles – Reverse Twist for Decorative Leather Seams

The Groz Beckert 34 (R TW) needle system—also listed under 287, 16X1, TFX1, 16X73, and PFX34—is specially crafted for sewing leather and technical materials where decorative stitching is required. The reverse twist point (R TW or LR) creates a lenticular incision at a 45° angle, producing a clean, slightly left-inclined seam ideal for visible topstitching on high-end leather goods.

Thanks to its flat shank at 90°, the needle seats securely in industrial sewing machines, maintaining precision alignment even during high-speed operations. Its chrome coating increases wear resistance and smooth thread movement, especially through dense or coated leather materials.
