Tool-flo 573625RN4C Grooving Insert GP50 Flo-lock

Product Description

The TOOL-FLO 573625RN4C is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. Manufactured to GP50 grade with a PVD-applied TiN coating, this right-hand insert delivers consistent cutting performance in steel and secondary workpiece materials. The insert features a 0.1252 inch (3.18 mm) cutting width and a maximum depth of cut of 0.1800 inch (4.57 mm), making it well suited for grooving applications that demand dimensional accuracy and repeatable tool life. It belongs to the Flo-Lock series and carries an FLGP-3125R ISO designation.

This insert is intended for use in professional machining environments, including production shops and job shops running steel components on CNC turning equipment. The Flo-Lock series is engineered for secure insert clamping and rigid tool engagement, reducing deflection during grooving passes. The positive rake geometry and 3-degree lead angle promote efficient chip evacuation and reduced cutting forces. It is appropriate for both roughing and finishing grooving operations within its specified depth-of-cut range of 0.1500 to 0.2000 inch (4.00 to 5.00 mm).

Key Features

• GP50 carbide grade with PVD TiN coating for extended wear resistance in steel
• Right-hand cutting orientation for standard OD grooving setups
• Cutting width of 0.1252 inch (3.18 mm) for precise groove sizing
• Maximum depth of cut of 0.1800 inch (4.57 mm)
• Positive rake angle of 55 degrees promotes low cutting forces and clean chip flow
• Corner radius range of 0.0050 to 0.0100 inch for controlled edge geometry

Compatibility

Designed for use in Flo-Lock series toolholders accepting the FLGP insert style with size code 3125 and a gage diameter of 0.3750 inch (3/8 inch). Confirm toolholder seat geometry matches the FLGP-3125R ISO code before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician following the toolholder manufacturer's torque and clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the toolholder seat and clamp for wear or debris before seating the new insert. Do not exceed the maximum depth-of-cut rating for this insert grade and geometry.
