Value Collection 2877086 Threading Insert 60V 3/8 Inch Ic Tin

Product Description

The VALUE COLLECTION 2877086 is a solid carbide on-edge threading insert designed to cut both external and internal 60-degree V-form threads. It carries a PVD Titanium Nitride (TiN) finish that extends edge life and reduces built-up edge during threading passes. The insert follows TPMC style geometry with a 3/8-inch inscribed circle (IC) and a thickness of 0.1250 inches. It is suited for use in CNC lathes and turning centers where precise thread form control is required. Machinists and toolroom operators in production and job-shop environments are the primary installers of this insert.

This threading insert is applied in turning operations that require a consistent 60-degree V thread profile on a range of materials. The C3 material grade carbide substrate is appropriate for threading steel, stainless steel, and similar ferrous workpieces at moderate to higher cutting speeds. The TiN coating improves surface hardness and provides a visual wear indicator. Typical applications include threading of shafts, fittings, bolts, and pipe connections where a standard 60-degree V form is specified.

Key Features

• Solid carbide construction with manufacturer grade TCN55 for consistent edge integrity
• PVD TiN coating reduces friction and extends tool life in ferrous threading applications
• Cuts both external and internal 60-degree V thread forms from a single insert style
• 3/8-inch inscribed circle (IC) fits standard TPMC-style threading toolholders
• 0.1250-inch thickness provides stable seating in on-edge insert pockets
• C3 material grade substrate balances hardness and toughness for general threading work

Compatibility

Designed as a direct-fit replacement for TPMC-style on-edge threading insert pockets with a 3/8-inch IC specification. Confirm toolholder insert style and pocket geometry before installation.

Installation Notes

Threading inserts are installed and indexed by qualified machinists operating CNC or manual turning equipment. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and can crack under excess clamp force. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and thread form accuracy.
