Frequently asked questions
1. What threads is the 11 ER A55 MTA insert suitable for?
The insert is mainly designed for BSP (British Standard Pipe) inch external threads with a fifty-five degree apex angle. It is also possible to use in Whitworth English BSW and BSF threads with the same angle. The pitch range includes P 0.5-1.5 mm and TPI 48-16 turns per inch.
2. What is the difference between an ER insert and an IR insert?
The designation ER (External Right) means external right-hand thread, while IR (Internal Right) is for internal threads. The ER insert is used for threading shafts, rods and pipes externally, while IR is used for threading holes. They are not interchangeable.
3. Can I use the insert for metric threads?
No, the A55 insert has a tip angle of fifty-five degrees dedicated only to BSP and Whitworth inch threads. For metric threads, you need an A60 insert with a sixty-degree angle according to the ISO standard. Using the wrong insert will result in an incorrect thread profile and dimensional inconsistency.
What is the height of the turned thread outline
H1 - Height of thread outline given in [mm] || P - pitch of thread given in [mm]
H1 [mm]=0.54127*P
