Vargus 51862 Laydown Threading Insert Carbide Tialn

Product Description

The VARGUS 51862 is a laydown threading insert designed for internal threading operations on CNC lathes and turning centers. Made from micrograin carbide with a TiAlN coating applied via PVD process, this insert delivers wear resistance and edge retention when cutting internal threads. It covers a threads-per-inch range of 14 to 8 TPI using a partial profile 60-degree thread form. The right-hand orientation and FS fully sintered series construction make it a reliable choice for production threading in ferrous and non-ferrous materials. Machinists and CNC operators in job shops and production environments use this insert for precision internal thread generation.

This insert is suited for internal threading applications where a partial profile 60-degree included angle is required. The 3FSIR insert style with an FS inscribed circle size of 3/8 inch fits compatible laydown threading toolholders. The F chipbreaker geometry supports controlled chip evacuation during internal thread cutting. It is commonly used in production turning, repair shops, and contract machining environments where consistent thread quality across a 14 to 8 TPI range is needed.

Key Features

• Micrograin carbide substrate for improved edge strength and wear life
• TiAlN coating via PVD process for heat and oxidation resistance
• Partial profile 60-degree thread form covers 14 to 8 TPI range
• Right-hand cutting orientation for standard internal threading
• FS fully sintered series with 3/8 inch inscribed circle
• F chipbreaker geometry for chip control in internal threading

Compatibility

Designed as a laydown threading insert in the 3FSIR style for use in compatible FS-series internal threading toolholders that accept a 3/8 inch inscribed circle laydown insert. ISO code reference is 16FSIRG60FST.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before seating or replacing the insert. Ensure the toolholder pocket and seating surface are clean and free of chips before installation. Follow the toolholder manufacturer torque specifications for the clamping screw to avoid insert cracking or improper seating.
