Tool-flo 594062LJ5R Grooving Insert FLR4062 GP3 Left Hand

Product Description

The TOOL-FLO 594062LJ5R is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the FLR-4062L ISO code and manufactured in the GP3 grade from micrograin carbide, this left-hand insert delivers a 0.1252 inch (3.18 mm) cutting width and a maximum depth of cut of 0.2500 inch (6.35 mm). A PVD-applied TiN coating reduces edge wear and improves surface finish in demanding cuts. The full-radius geometry and positive rake angle at 55 degrees make it well suited for finishing passes where surface quality and tool life consistency are critical. Machinists and CNC operators working in job shops and production environments are the primary installers and users.

This insert is configured for left-hand cutting in the Flo-Lock series, which uses a secure mechanical clamping system for repeatable insert indexing. The GP3 micrograin carbide grade performs reliably in general-purpose grooving with particular effectiveness on stainless steel and similar difficult-to-machine materials. The 3/8 inch gage diameter and a lead angle of 3 degrees align with standard Flo-Lock toolholders. Typical applications include groove turning, undercut machining, and snap-ring groove generation on turned parts in both low-volume and high-production settings.

Key Features

• Full-radius insert geometry with positive 55-degree rake angle for clean, low-force cuts
• Left-hand cutting orientation, ISO code FLR-4062L
• 0.1252 inch (3.18 mm) cutting width with a maximum depth of cut range of 0.2000 to 0.3000 inch (5.00 to 10.00 mm)
• GP3 manufacturer grade rated for stainless steel and general-purpose grooving applications
• Flo-Lock series compatibility for secure, repeatable insert clamping and indexing

Compatibility

Designed for use with Flo-Lock series toolholders accepting FLR-4062L style inserts with a 3/8 inch gage diameter. Suited for stainless steel and general-purpose workpiece materials as specified by the GP3 grade designation.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and Flo-Lock clamping hardware as specified by the toolholder manufacturer to ensure secure seating. Inspect the insert pocket and clamping screw for wear or damage before each installation to prevent premature insert failure or dimensional inaccuracy.
