Tungaloy 6804980 Grooving Insert JTGR3075F J740 Solid Carbide

Product Description

The TUNGALOY 6804980 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. It carries the JTGR3075F insert style designation and is manufactured in the J740 grade with a PVD-applied TiN coating. The insert provides a 0.75 mm cutting width and a maximum depth of cut of 1.9 mm, making it suited for narrow, shallow grooving work where dimensional accuracy is critical. The right-hand orientation, screw-holding method, and Series J design make this a direct-fit choice for compatible TUNGALOY toolholding systems. Machinists and CNC turning specialists are the primary users.

This insert is intended for grooving stainless steel and steel workpieces, corresponding to ISO material codes M and P. The micrograin carbide substrate and TiN finish support stable cutting performance in these demanding materials. It is applicable in production turning environments where consistent groove width and controlled chip formation are required. The F chip breaker geometry is optimized for these material groups. The insert meets ISO 13399 standards for cutting tool data representation, which supports integration with CAM and tool management software used in modern machine shops.

Key Features

• Solid micrograin carbide substrate for rigidity and wear resistance in steel and stainless steel
• PVD-applied TiN coating for extended tool life and reduced built-up edge
• 0.75 mm cutting width with a maximum depth of cut of 1.9 mm for narrow grooving applications
• Right-hand orientation with screw holding method for secure, repeatable seating
• F chip breaker geometry tuned for stainless steel and steel ISO M and P material groups
• Compliant with ISO 13399 cutting tool data standards

Compatibility

Designed for use with TUNGALOY Series J grooving toolholders that accept JTGR-style inserts secured by screw clamp. Confirm toolholder insert seat specification before ordering.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the screw clamp to the toolholder manufacturer specification - do not overtighten. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and runout.
