Tool-flo 574050RN4E Grooving Insert GP50 Solid Carbide

Product Description

The TOOL-FLO 574050RN4E is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to the FLG-4250R ISO code in the Flo-Lock series, this right-hand insert carries a PVD-applied TiN coating over a GP50 grade carbide substrate. It delivers a 0.2500-inch (6.35 mm) cutting width and a maximum depth of cut of 0.2500 inches (6.35 mm). The positive rake geometry and 55-degree rake angle reduce cutting forces and support clean chip evacuation. This insert is intended for installation and replacement by machinists and tool-crib technicians in production and job-shop turning environments.

The 574050RN4E is suited for grooving and parting operations on steel workpieces in both production and maintenance machining contexts. Its FLG insert style and 4250 insert size make it appropriate for use in compatible Flo-Lock toolholders wherever right-hand orientation is required. The GP50 grade and TiN finish make it a practical choice for general-purpose steel turning at moderate cutting parameters.

• Positive rake geometry with 55-degree rake angle for reduced cutting forces
• Corner radius range of 0.0200 to 0.0250 inches for controlled edge geometry
• Right-hand orientation; ISO code FLG-4250R

Compatibility

Designed for use in Flo-Lock series toolholders accepting FLG-style inserts in the 4250 size. Gage diameter is 0.3750 inches (3/8 inch). Verify toolholder and pocket specifications against the FLG-4250R ISO code before ordering.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine powered down and the spindle locked. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer - do not overtighten or substitute fasteners. Inspect the toolholder pocket and clamping surfaces for wear or debris before seating the new insert. Follow your facility safety procedures and applicable OSHA machine-guarding requirements when working on turning equipment.
