Tool-flo 563889RN4C Grooving Insert GP50 Solid Carbide Tin

Product Description

The TOOL-FLO 563889RN4C is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Built to GP50 grade with a TiN (titanium nitride) PVD coating, this right-hand insert delivers consistent cutting performance in ferrous and stainless steel applications. It features a 4.80 mm (0.189 inch) cutting width and a maximum depth of cut of 4.57 mm (0.180 inch). The positive rake geometry and 55-degree rake angle reduce cutting forces and improve chip control. This insert is part of the Flo-Lock series and is intended for installation by machinists and CNC tooling technicians.

This insert is suited for grooving operations on steel and stainless steel workpieces in both production and job-shop environments. The FLG insert style with ISO code FLG-3189R fits Flo-Lock compatible toolholders. With a gage diameter of 0.375 inch (3/8 inch) and an overall width of 0.195 inch, it is appropriate for tight-tolerance external grooving on turned components where repeatable depth and width are required. The C5 and C6 material grade ratings make it suitable for a range of ferrous cutting conditions.

Key Features

• Solid carbide construction with PVD-applied TiN coating for extended wear resistance
• 4.80 mm cutting width with a maximum depth of cut range of 4.00 to 5.00 mm (0.150 to 0.200 inch)
• Positive rake angle of 55 degrees for reduced cutting forces and improved chip flow
• Right-hand cutting orientation, ISO code FLG-3189R
• Corner radius range of 0.020 to 0.025 inch for controlled edge geometry
• Compatible with stainless steel and general ferrous workpiece materials at C5 and C6 grade

Compatibility

Designed for use in Flo-Lock series toolholders accepting the FLG insert style, size 3189. The ISO code FLG-3189R identifies the compatible holder interface. Verify toolholder specifications against insert dimensions before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the insert pocket is clean and free of chips or debris before clamping. Follow the toolholder manufacturer's clamping torque specifications and consult applicable shop safety procedures during changeover.
