Tool-flo 573050LN4E Grooving Insert GP50 Left Hand Carbide

Product Description

The TOOL-FLO 573050LN4E is a solid carbide grooving insert engineered for precision grooving and parting operations on CNC lathes and turning centers. Built to the FLG3250 insert style in manufacturer grade GP50, this left-hand insert features a 0.25-inch (6.35 mm) cutting width and a maximum depth of cut of 0.18 inches (4.57 mm). The carbide substrate receives a PVD-applied TiN coating for improved wear resistance and extended tool life. It belongs to TOOL-FLO's Flo-Lock series, which uses a clamp-style insert holding method for secure, repeatable seating during interrupted and continuous grooving cuts. Licensed machinists and CNC turning technicians are the primary installers and users of this insert.

This insert is suited for grooving operations on a range of workpiece materials, with stainless steel listed as a secondary workpiece material, making it a viable choice in shops handling corrosion-resistant alloy components. The Flo-Lock series is designed for external grooving applications in production turning environments, both in job shop and manufacturing settings. The GP50 grade and TiN PVD coating combination targets applications where a balance of toughness and surface hardness is needed. The left-hand designation determines the direction of tool approach and must be matched to the toolholder orientation and machine setup before ordering.

Key Features

• Solid carbide construction with PVD-applied TiN coating for wear resistance
• 0.25-inch (6.35 mm) cutting width for consistent groove sizing
• Maximum depth of cut of 0.18 inches (4.57 mm); operating range 0.15 to 0.20 inches (4.00 to 5.00 mm)
• Left-hand insert orientation for specific toolholder compatibility
• Corner radius in the range of 0.020 to 0.025 inches for controlled edge geometry
• Clamp-style insert holding method for secure and repeatable seating
• Suitable for stainless steel and comparable workpiece materials

Compatibility

This insert corresponds to ISO code FLG3250L and manufacturer catalog number FLG-3250L within the Flo-Lock series. It is designed for use in compatible TOOL-FLO Flo-Lock clamp-style grooving toolholders that accept the FLG3250 insert size and left-hand orientation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Before changing inserts, ensure the machine spindle is fully stopped and the control is in a safe, locked-out state per shop lockout/tagout procedures. Seat the insert fully against the toolholder pocket before tightening the clamp to avoid insert movement during cutting. Verify insert hand orientation and cutting direction against the programmed toolpath before resuming operation.
