We could prodce different standards threading inserts, all items are made by general-purpose grade M25, which could apply for different workpiece. The excellent hardness and wear resistance. All grinding process are employed auto-cnc, which could get great tolrence, smooth surface. The 3 µm coating thickness, TiN+TiAlN multi-layer coating has perfect smooth surface and improve the performance of threading Inserts. It is your best cost effective selection.
We have Internal and external British Standard Pipe Thread (BSPT) 55° threading inserts, the technical data and codes are as follows:
06NR/L BSPT: TPI 28; 06NR/L 28 BSPT;
08BR/L BSPT: TPI 28,19; 08NR/L 19 BSPT
11NR/L BSPT: TPI 28, 19, 14; 11NR/L 14 BSPT;
16ER/L BSPT, 16NR/L BSPT: TPI:28, 19, 14, 11; 16NR/L 8 BSPT;
