The 332 LL LG needle (needle system ARX332) has a left cutting point (135°) 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 Chandler (classes 600 BR, 600 BR 500, 600, 600 - 75-D), Pfaff (classes 3300, 3306, 3300 - 958-01- 29, 3300 - 958-01- 30) and Dürkopp Adler (classes 030, 030 - OTHER CLASS).
Thinner needle sizes are used, among others, for medium-weight leather for everyday leather goods and saddlery work, and the thicker versions 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.
