The 1000 H Q needle (needle system 1000) has a square point (45°) 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 Dürkopp Adler (classes 020 - 17-B, 120 - 17 B TO 17 B-S, 120 - 37 TO 37 SI), Keestar (classes 733, KES SERIES) and Seiko (classes SAM - 20, SLH - 2).
The available needle sizes are used, among others, for very thick, firm leather and multi-layer leather joins. As sewing thread, a bonded polyester or nylon thread such as Amann Serabond, Amann Strongbond or Coats Dabond is usually recommended, in a thickness matching the needle size chosen. A cutting point is required here to create clean puncture channels in firm materials.
