Tool-flo 562825PRN4C Grooving Insert FLG2125CB GP50

Product Description

The TOOL-FLO 562825PRN4C is a solid carbide grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. Built to the FLG-2125R-CB ISO designation and manufactured to GP50 grade, this insert features a Physical Vapor Deposition (PVD) TiN coating that extends edge life in demanding cutting conditions. The right-hand orientation, positive rake angle of 55 degrees, and CB chip breaker geometry work together to control chip flow and reduce cutting forces. With a cutting width of 0.1252 inches and a maximum depth of cut of 0.1100 inches, this insert is suited for tight-tolerance grooving where repeatability matters. It is installed and changed by machinists and CNC tooling technicians.

This insert is used in high-production turning applications on ferrous metals, with stainless steel listed as a secondary workpiece material. The Flo-Lock series interface ensures secure seating in compatible FLG-style toolholders, making it appropriate for both interrupted and continuous groove cuts. The 0.0050 to 0.0100 inch corner radius range and lead angle of 3 degrees are well suited to shallow groove profiles and finish-critical operations in manufacturing and repair environments.

Key Features

• Solid carbide construction with PVD TiN coating for extended wear resistance
• GP50 grade rated for material grades C5 and C6 workpiece materials
• CB chip breaker geometry promotes positive chip control at the cutting edge
• Right-hand cut orientation with a positive 55-degree rake angle
• Gage diameter of 0.1875 inches (3/16 inch) for precise insert positioning
• Flo-Lock series interface for repeatable seating in FLG-style toolholders

Compatibility

Designed for use in FLG-style Flo-Lock series grooving toolholders that accept the 2125CB insert size. ISO code FLG-2125R-CB identifies the exact toolholder pocket required.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torx or clamp screw driver specified by the toolholder manufacturer to seat the insert firmly without overtightening. Inspect the toolholder pocket for wear or debris before seating a new insert to ensure proper clamping and edge geometry.
