16ER AG55 (55) Threading Insert is a universal partial-profile external threading carbide insert designed for cutting 55 thread forms such as BSP, BSPT, Whitworth, and other British standard threads on CNC lathes.

In how many pitches can it be used?
Since the AG55 is a partial-profile insert, it can cut multiple thread pitches within the 55 thread standard rather than being limited to a single pitch.

48 TPI to 8 TPI (imperial threads)

Uses:

• External BSP and BSPT pipe threading.
• External Whitworth thread cutting.
• Multi-pitch threading with a single insert.
• CNC lathe and turning center operations.
• Maintenance, repair, and production machining.
• Machining steel, stainless steel, cast iron, and alloy materials.
• Reduces tooling inventory by covering many thread pitches.
