Tool-flo 563678LJ5R Grooving Insert GP3 Solid Carbide Tin

Product Description

The TOOL-FLO 563678LJ5R is a solid carbide left-hand grooving insert in the Flo-Lock series, designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured from micrograin carbide with a PVD-applied TiN coating, it delivers a cutting width of 1.98 mm (0.0780 inches) and a maximum depth of cut of 3.05 mm (0.1200 inches). The GP3 grade and positive rake geometry support clean chip formation and reduced cutting forces in a range of workpiece materials. Licensed machinists and CNC turning specialists install and index this insert during scheduled tooling maintenance.

This insert is suited for external and internal grooving applications in production turning environments, both light manufacturing and high-cycle production shops. The FLG-3078L ISO code and insert style FLG place it in a standardized tool holder format common to the Flo-Lock system. The left-hand orientation, 3-degree lead angle, and 55-degree rake angle make it appropriate for specific approach directions and part geometry requirements on horizontal and vertical turning machines.

Key Features

• Solid micrograin carbide substrate for wear resistance and edge stability
• PVD TiN coating for reduced friction and extended tool life
• Positive rake angle (55 degrees) reduces cutting forces and heat generation
• Cutting width of 1.98 mm with a maximum depth of cut of 3.05 mm
• Left-hand insert orientation for specific turning approach requirements
• Corner radius range of 0.0050 to 0.0100 inches for controlled edge geometry

Compatibility

Designed for use with Flo-Lock series toolholders accepting FLG-style inserts in size 3078, with a gage diameter of 3/8 inch (0.3750 inches).

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the machine in a full stop, locked-out, and de-energized state per applicable lockout/tagout procedures. Use appropriate insert seating tools to ensure the insert is fully seated and clamped before resuming cuts. Inspect the toolholder pocket for wear or debris before installing a new insert. Follow the toolholder manufacturer torque specifications for clamping screws.
