LEFT TWIST NARROW WEDGE POINT "PCL"

Groz Beckert 34 PCL / 287PCL Industrial Leather Sewing Machine Needles – Chrome-Coated with Narrow Wedge Point

The Groz Beckert 34 PCL (also listed as 287PCL, TFX4, 16X4NW) is a high-performance industrial needle designed for leather sewing applications, particularly where high-strength seams and thread protection are critical. With a PCL (Narrow Wedge Point with left-side groove), this needle creates a lenticular (lens-shaped) incision across the seam direction—ideal for strong, tear-resistant seams in footwear, car seats, leather bags, and accessories.

The left-twist groove below the eye makes this needle particularly suitable for right-positioned hook machines or as the left-hand needle in twin-needle lockstitch setups. The groove protects the thread as the needle exits the leather, reducing friction and thread damage caused by the cutting edge.
