Frequently asked questions
1. What threads is the 22 IR N55 HTA insert suitable for?
The insert is designed for Whitworth (BSW, BSF) inch threads with an apex angle of 55 degrees. The N55 incomplete profile supports a pitch range of P=3.5-5 mm, which makes it possible to produce BSW 1 1/8-7, BSW 1 1/4-7, BSW 1 1/2-6, BSW 1 3/4-5 and other British threads in this pitch range.
2. How does the N55 incomplete profile differ from the full profile?
The incomplete profile (N55) is a universal insert for inch threads, which allows you to turn different pitches in the range of 3.5-5 mm with one tool. An insert with a solid profile would be dedicated to only one specific pitch, but would offer slightly better surface quality. The incomplete profile is the optimal solution for workshops working with different inch threads.
3. Can the 22 IR N55 insert be used for external threads?
Yes, despite the IR (Internal Right) designation, this insert is interchangeable and can be used as an external left (EL) for inch threading. It requires a toolholder size of 22 mm. Make sure the insert sticks to the socket with its entire surface to ensure stability when threading Whitworth threads on the lathe.
4. What is the height of the turned thread outline for this insert?
H1 - Height of thread outline given in mm || P - pitch of thread given in mm
H1 = 0.54127 * P
