135x16 TRI, DPx16 D — SCHMETZ industrial sewing machine needles for leather, 10 pcs.

SCHMETZ 135x16 TRI, also known as DPX16 D are industrial sewing machine needles for leather with a D (Triangular Point) triangular cutting point. The needle tip has a triangular cross-section, which provides a very strong cutting effect and a straight, well-defined stitch line. Ideal for hard, dry leather and thicker technical materials. Chrome coating reduces friction and heat, ensuring a long service life in intensive use.

🧵 Suitable materials

• Hard, dry leather (including multiple layers)
• Heavy footwear, work/maintenance footwear (e.g., safety boots)
• Upholstery and furniture fabrics
• Plastic, cardboard, thick board, paper

✨ Where the D needle excels

• Coarse and regular seams in hard leather and technical materials
• Crossing seams, where a secure, durable stitch is needed
• Manufacture of heavy footwear and protective footwear

• Technical products made from plastic and cardboard

🎯 Advantages of D (Triangular Point)

• Strongest cutting effect among cutting points – easily cuts into hard materials
• Straight seam with a clearly visible stitch pattern
