Tool-flo 573625LN4C Grooving Insert GP50 Carbide Tin

Product Description

The TOOL-FLO 573625LN4C is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Part of the Flo-Lock series, it features a left-hand cut orientation with a 0.1252 inch (3.18 mm) cutting width and a maximum depth of cut of 0.1799 inch (4.57 mm). The insert is manufactured from carbide grade GP50 and coated with TiN via a PVD process, providing wear resistance suited to steel and similar secondary workpiece materials. Machinists and tooling specialists install this insert into compatible Flo-Lock toolholders as part of a production or job-shop turning setup.

This insert is intended for grooving applications on turning machines where left-hand tool orientation is required. The positive rake angle of 55 degrees and a 3-degree lead angle make it well-suited for controlled chip flow during groove-cutting in steel materials. The 3/8 inch (0.3750 inch) gage diameter and 0.3440 inch cutting height are consistent with standard Flo-Lock insert seating. It is applicable in both production turning environments and general-purpose machining shops where repeatable groove geometry is critical.

Key Features

• Solid carbide construction with GP50 grade - rated for material grades C5 and C6
• TiN coating applied via PVD process for enhanced surface wear resistance
• Left-hand cut orientation for specific toolholder and approach configurations
• Cutting width of 0.1252 inch (3.18 mm) for consistent groove sizing
• Maximum depth of cut of 0.1799 inch (4.57 mm) within a range of 0.1500 to 0.2000 inch
• Positive rake at 55 degrees promotes controlled chip formation during grooving

Compatibility

Designed for use with Flo-Lock series grooving toolholders that accept the FLGP-3125L insert style. Verify toolholder insert pocket specifications before installation to confirm proper seating and clamping.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer - do not overtighten the clamp screw. Confirm insert seating and edge orientation before resuming cutting operations.
