Industrial Sewing Machine Needles SCHMETZ DPx5 (134) DH for Leather - 10 pcs.

SCHMETZ 134 DH Industrial Sewing Machine Needles are needles for technical materials with a DH (Half triangular point) cutting tip. This tip type has a half-triangular cross-section (smaller than the D point), which creates a narrow cut in the material and forms a straight, firm seam without pulling the material. Ideal for coarse and normal seams, as well as cross seams on thicker coated materials.

🧵 Suitable materials

• Composite materials (e.g., laminated materials combined with plastic sections)
• Plastic parts and plastic sections
• Rigid cardboard
• Canvas and tarpaulin materials
• Tent and awning fabrics
• Other technical coating materials

✨ Where DH excels

• Coarse and normal seams on technical fabrics and coatings
• Cross seams and joints where material thickness changes
• Car interior trim, seats, panels
• Sewing tarpaulins, tents, and awnings

🎯 DH (Half triangular point) advantages

• Narrower cut than the classic D point – less material damage
• Clean, straight stitch even in thick coated materials
• Stable sewing without significant needle deviation
• Especially suitable for technical, structural seams, not just decorative effect

🧶 Thread recommendations for technical materials

Guideline recommendations when choosing thread and needle for DH point:

• For coarse structural seams (tarpaulins, tent fabrics, reinforcement strips): polyester / polyamide tex 75–150 (approximately No. 20–8) with needle NM 120–160
• For normal seams (car interior trim, upholstery, cardboard): polyester tex 40–75 (approximately No. 40–30) with needle NM 100–140

It is always advisable to test the exact combination on the specific material.
