Tool-flo 562631LJ5R FLG2031 GP3 Grooving Insert Solid Carbide

Product Description

The TOOL-FLO 562631LJ5R is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Built to the FLG2031 insert style in manufacturer grade GP3, this left-hand insert features a TiN (titanium nitride) coating applied via PVD process, which improves wear resistance and extends tool life in ferrous and non-ferrous machining. The micrograin carbide substrate provides edge stability at close tolerances. With a cutting width of 0.79 mm and a maximum depth of cut of 1.27 mm, this insert is suited for fine grooving work where dimensional accuracy is critical. It is installed by machinists and toolroom technicians working to tight part specifications.

This insert is part of the Flo-Lock series, designed for grooving applications requiring precise width control and consistent depth. The left-hand orientation suits setups where the tool approaches from the left side of the workpiece. Its positive rake geometry reduces cutting forces, making it appropriate for smaller diameter workpieces and finishing cuts where surface finish quality matters. The ISO code designation FLG-2031L identifies this insert within standardized tooling systems, simplifying replacement ordering and toolholder matching.

Key Features

• Solid micrograin carbide substrate for edge strength and dimensional stability
• TiN coating via PVD process for improved wear resistance
• Positive rake angle (55.00 degrees) reduces cutting forces during grooving
• Left-hand cut orientation (ISO code FLG-2031L)
• Cutting width of 0.79 mm with corner radii from 0.0020 to 0.0050 inches
• Full radius: No - flat-bottom groove profile

Compatibility

Designed for use with Flo-Lock series toolholders accepting FLG-2031L style inserts with a 3/16 inch gage diameter. Confirm toolholder compatibility with the FLG insert style and 2031 size code before ordering.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing any insert. Use the appropriate torx or hex key as specified by the toolholder manufacturer - do not overtighten the clamping screw. Verify insert seating and orientation before resuming cutting operations, and confirm the left-hand designation matches the programmed tool path direction.
