Tool-flo 563694LN4C Grooving Insert GP50 Flo-lock

Product Description

The TOOL-FLO 563694LN4C is a solid carbide grooving insert designed for precision external grooving and cutoff operations on CNC lathes and turning centers. Built to the FLG insert style in the 3094 size, it delivers a cutting width of 0.0941 inches (2.39 mm) and a maximum depth of cut of 0.1799 inches (4.57 mm). The GP50 grade substrate is finished with a PVD-applied TiN coating for improved wear resistance and edge retention. This is a left-hand insert with a positive rake angle of 55 degrees, suited for machinists and tooling specialists working in production turning environments.

This insert fits within the Flo-Lock series toolholding system and is intended for use in grooving applications on ferrous materials including stainless steel. The positive rake geometry reduces cutting forces on tighter setups. The 3/8-inch (0.3750 inches) gage diameter and overall width of 0.1950 inches make it compatible with Flo-Lock style holders designed for the 3094 insert size. Typical applications include groove forming, undercut machining, and snap-ring groove production in both job shop and production environments.

Compatibility

Designed for use with Flo-Lock series grooving toolholders accepting FLG-3094L inserts (ISO code FLG-3094L). Rated for material grades C5 and C6, with secondary workpiece material suitability for stainless steel.

Installation Notes

Installation is performed by a machinist or tooling technician following the toolholder manufacturer's seating and clamping procedure for Flo-Lock style inserts. Ensure the machine spindle is fully stopped and the turret is in a safe indexed position before changing inserts. Use the correct insert seating tool or torx key specified by the toolholder to achieve proper clamping force - do not over-torque the clamping screw. Verify insert orientation (left-hand) matches the programmed tool path before resuming cutting operations.
