The B-27 P needle (needle system B-27) has a pearl point 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 Siruba (classes 401, 504, 505F1-04, 512 to 514), Kingtex (classes SH, SHF, SK, SH-7002-032-M02) and Yamato (classes 74 Series, 78 Series, AEF, AFZ).
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.
