Industrial Sewing Machine Needles SCHMETZ DPx16 D-135x16 TRI for Leather

SCHMETZ DPx16 D also known as 135X16 TRI, DPX16 D industrial sewing machine needles for leather with D (Triangular Point) triangular cutting point. The needle point has a triangular cross-section, which provides a very strong cutting effect and a straight, pronounced 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 multi-layer)
• Heavy footwear, work/maintenance footwear (e.g., safety boots)
• Upholstery and furniture trim
• Plastic, cardboard, thick pressboard, paper

✨ Where the D needle shines

• Rough and standard seams in hard leather and technical materials
• Cross seams, where a secure, durable stitch is needed
• Manufacturing of heavy footwear and protective footwear
• Sewing furniture and automotive upholstery
• Technical products made of plastic and cardboard

🎯 Advantages of D (Triangular Point)

• Strongest cutting effect among cutting points – easily cuts into hard material
• Straight seam with a clearly visible stitch pattern
• Very suitable for areas where mechanical strength and a secure bond are important
• Stable performance even with thicker threads and multiple material layers

🧶 Recommended threads for leather

Needle size and thread size should be selected according to material thickness and the purpose of the seam – the thicker and harder the leather, the larger the needle and the coarser the thread.
