The 134 SD1 needle (needle system 134) has a round point with small triangular cutting edge for working leather, synthetic leather and other coated materials – never for woven fabric, since the cutting action would sever the weave threads. It is used in industrial sewing machines for leather and synthetic-leather work, where the cutting point produces a clean puncture. Suitable machine classes are found, among others, at Pfaff (classes 22, 28, 33905, 34), Juki (classes ACB, ACF, AEC, ALS) and Singer (classes 20, 61, 107, 108).
In size NM:80/SIZE:12, this version is especially well suited to thinner to medium-weight leather. A sewing thread in the range Nm 80/2 to Nm 50/2 is usually suitable; a bonded polyester or nylon thread such as Amann Serabond, Amann Strongbond or Coats Dabond is recommended. A cutting point is required here to create clean puncture channels in firm materials.
