Frequently Asked Questions
Q: What thread profile do the AG60-S inserts produce?
A: The AG60-S designation refers to a 60° thread form, which is compatible with both metric (M) and unified (UN/UNC/UNF) thread standards — making these inserts highly versatile for general-purpose threading on CNC lathes and turning centers.
Q: What is the difference between the MMT16ER and 16IR insert?
A: The MMT16ER is designed for external (OD) threading, used to cut threads on the outside of a workpiece, while the 16IR is for internal (ID) threading, used to cut threads inside a bore or hole. Both share the same AG60-S thread form and VP15TF carbide grade.
Q: Which toolholders are compatible with these inserts?
A: These inserts are designed to fit standard 16ER and 16IR series threading toolholders, which are widely available and commonly used in most CNC and manual lathes. Always verify your toolholder's insert seat size before ordering.
Q: What materials can the VP15TF grade machine?
A: The VP15TF PVD-coated carbide grade is optimized for threading carbon steel, alloy steel, and stainless steel. Its PVD coating provides excellent edge sharpness and wear resistance for consistent thread quality over extended production runs.
