To machine the corresponding internal thread, choose any insert NTC crest turning insert NTC crest turning insert that will cut a unified class 2B thread, then bore the minor diameter to size. for (P ) 2mm) and finer. for (P * 3mm) and coarser. Refer to SAE8879C and MIL-S-8879C and SAEAS8879D for the correct “J” thread minor diameter values. NOTE: NTC inserts automatically control root to crest dimensions. Therefore, in setting up threading operations with NTC inserts, check the O.D. or I.D. at the thread crest for correct dimensions. 60° V-Thread Application Data recommended TPI* recommended TP* insert D E description insert (mm) (mm) external internal external internal NT-1 1,90 1,11 – 24–12 – 1,00–2,00 NT-2 28,70 1,90 36–8 20–7 0,70–3,00 1,25–3,50 radius NT-2-K 28,70 1,90 36–8 20–7 0,70–3,00 1,25–3,50 NTF-2 15,75 1,01 44–14 24–12 0,60–1,75 1,00–2,00 NTK-2 15,75 1,01 44–14 24–12 0,60–1,75 1,00–2,00 NTP-2 28,70 1,90 36–8 20–7 0,70–3,0 1,25–3,50 NT-3 37,59 2,46 20–6 12–5 1,25–4,00 2,00–5,00 feed direction NT-3-K 37,59 2,46 20–6 12–5 1,25–4,00 2,00–5,00 NT-3-C 37,59 2,46 11–6 6 (only) 2,50–4,00 4,00 (only) NT-3-CK 37,59 2,46 11–6 6 (only) 2,50–4,00 4,00 (only) NTF-3 21,08 1,37 44–10 24–9 0,60–2,50 1,00–2,50 NTK-3 21,08 1,37 44–10 24–9 0,60–2,50 1,00–2,50 radius NTP-3 37,59 2,46 20–6 12–5 1,25–4,00 2,00–5,00 NT-4 49,78 3,22 20–4 12–4 1,25–6,25 2,00–6,25 NT-4-K 49,78 3,22 20–4 12–4 1,25–6,25 2,00–6,25 feed direction NT-4-C 49,78 3,22 11–4 1/2 6–4 1/2 2,50–5,50 4,00–5,50 NT-4-CK 49,78 3,22 11–4 1/2 6–4 1/2 2,50–5,50 4,00–5,50 NTF-4 21,08 1,37 44–10 24–9 0,60–2,50 1,00–2,50 NTK-4 21,08 1,37 44–10 24–9 0,60–2,50 1,00–2,50 NTP-4 49,78 3,22 20–4 12–4 1,25–6,25 2,00–6,25 *Based on maximum insert radius size and class 2A and 2B thread specifications. widia.com F93
