Tool-flo 563678LN4C Grooving Insert GP50 Left Hand

Product Description

The TOOL-FLO 563678LN4C is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. This left-hand insert carries a GP50 manufacturer grade with a TiN (titanium nitride) PVD coating for extended tool life and reduced built-up edge. The cutting width measures 1.98 mm (0.078 inches) with a maximum depth of cut of 3.05 mm (0.1201 inches). It features a positive rake angle of 55 degrees and a lead angle of 3 degrees, supporting clean chip evacuation in tight-groove applications. Machinists and toolroom professionals install this insert in compatible Flo-Lock series toolholders.

This insert is suited for grooving operations on steel, and is rated for use on stainless steel as a secondary workpiece material. The FLG-3078L ISO code places it in the Flo-Lock insert family, which is commonly used in production turning environments where repeatable groove geometry and insert indexability matter. It is not a full-radius insert; corner radius range is 0.0050 to 0.0100 inches. The 3/8-inch (0.3750 inches) gage diameter and 0.195-inch overall width suit standard Flo-Lock pocket configurations used across high-volume turning applications.

Key Features

• Maximum depth of cut 3.05 mm (0.1201 inches); operating range 3.00 to 4.00 mm
• Positive rake geometry at 55 degrees promotes clean cutting action and reduced cutting forces
• GP50 grade with C5/C6 material grade rating covers steel and stainless steel applications

Compatibility

Designed for use in Flo-Lock series toolholders accepting FLG-3078L ISO-coded inserts with a 3/8-inch gage diameter pocket. Verify toolholder pocket dimensions and hand orientation before ordering.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or toolroom technician following the toolholder manufacturer's torque specifications. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket for chips or debris before seating to ensure proper contact and prevent insert rocking. Follow applicable workplace safety standards for cutting tool handling.
