Industrial Sewing Machine Needles-SCHMETZ DPx16-135x16 DIA for Leather

Adatas for SCHMETZ DPx16 DIA industrial sewing machines, also known as 135X16 DIA, DPX16 DIA there are needles for leather with DI (Diamond point) cutting head. This tip type has a diamond-shaped cross-section, and the cut in the material is made At a 90° angle to the direction of the thread. As a result, the seam is very straight, slightly recessed (recessed), with a precise, firm stitch line without needle deviation even in hard, dry leather.

🧵 Suitable materials

• Hard, dry genuine leather
• Rigid faux leather and composite materials
• Leather products with multiple layers
• Thick, firm leather parts – soles, belts, inserts, etc.

✨ Where AI particularly excels

• Very straight, “recessed” seams that do not protrude above the leather surface
• Normal and coarser decorative seams with a clearly defined stitch pattern
• Seams in footwear, bags, and suitcases where maximum precision is required
• Places where it is important that the needle does not slip and does not “lift” the material

🎯 DI (Diamond point) advantages

• 4 cutting edges – the needle pierces heavy, tough leather more easily
• No needle deflection – the stitching follows a linear design, for perfectly straight seams
• Clean, professional stitch appearance without snagging the material
• Very straight seam – unlike the LR/VR slanted decorative stitching

Thread recommendations for leather

• For bolder decorative stitches (in bags, suitcases, shoes): polyester / polyamide tex 75–150 (No. 20–8) with needles NM 120–200
• For normal and medium-coarse seams: polyester tex 50–75 (No. 40–30) with needles NM 110–140
