Tool-flo 562825LN4C Grooving Insert GP50 Solid Carbide

Product Description

The TOOL-FLO 562825LN4C is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the FLG-2125L ISO code within the Flo-Lock series, this left-hand insert delivers a 0.1252 inch (3.18 mm) cutting width and a maximum depth of cut of 0.1098 inch (2.79 mm). The GP50 grade substrate is finished with a PVD-applied TiN coating, providing wear resistance and edge integrity across a range of workpiece materials including stainless steel. Cutting height measures 0.2190 inch, and the rake angle is 55 degrees positive.

This insert is suited for left-hand grooving applications on production turning equipment in both job shop and high-volume manufacturing environments. The Flo-Lock series is engineered for secure seating in compatible Flo-Lock toolholders, reducing insert movement during interrupted cuts and coolant-intensive operations. Secondary workpiece material compatibility includes stainless steel, making this insert a practical choice when machining corrosion-resistant alloys. It is typically installed by CNC machinists, tool-and-die technicians, and production lathe operators.

Key Features

• Solid carbide construction with PVD TiN coating for extended wear life
• Left-hand cutting orientation for dedicated left-hand grooving setups
• 3.18 mm (0.1252 inch) cutting width with full-depth range of 2.00 to 3.00 mm
• Positive 55-degree rake angle reduces cutting forces and heat generation
• Corner radius range of 0.0050 to 0.0100 inch for controlled edge geometry
• GP50 grade rated for material grades C5 and C6 applications
• Flo-Lock series design for positive insert retention in matched toolholders

Compatibility

Designed for use with compatible TOOL-FLO Flo-Lock series toolholders accepting FLG-2125L ISO-style left-hand grooving inserts. Verify toolholder seat geometry and insert pocket dimensions before installation.

Installation Notes

Insert replacement should be performed with the machine powered down and the spindle fully locked. Use the appropriate torque wrench and insert clamp screw specified by the toolholder manufacturer - do not overtighten clamping screws, as carbide inserts are brittle and susceptible to cracking under excess clamping force. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert. Follow the toolholder manufacturer's recommended clamping procedure for Flo-Lock style seats.
