Schmetz 134 DI Size 120 Industrial Sewing Machine Needles – Pack of 10

Size 19 – Diamond Point – Pack of 10

Compatible with: 134 DI, 135X8 DIA, DPX8 (CANU 20:05KJ1)

The Schmetz 134 DI Size 120 industrial sewing needles are made with a DI diamond cutting point, which creates a rhombic incision aligned with the seam direction. With four sharp cutting edges, these needles penetrate dense and heavy materials more easily than standard needle points, delivering straight, recessed seams that resemble the finish of an “S” narrow cross point. Chrome-coated for durability, they are engineered for reliable performance in industrial lockstitch machines.

Key Features:

• DI Diamond Point – Produces rhombic incisions with four cutting edges for smoother penetration.

• Straight, Recessed Seams – Creates strong, professional-looking seams in heavy materials.

• Heavy-Duty Use – Ideal for thick leather, coated fabrics, upholstery, and technical textiles.

• Industrial Lockstitch System – Compatible with 134 DI, 135X8 DIA, and DPX8 systems.
