Tool-flo 572431LAC3R Grooving Insert FLGP2031 AC3R Carbide

Product Description

The TOOL-FLO 572431LAC3R is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Part of the Flo-Lock series, this left-hand insert carries the AC3R manufacturer grade and features an AlTiN (aluminum titanium nitride) PVD coating for improved wear resistance and heat management at the cutting edge. The insert delivers a cutting width of 0.031 inches (0.79 mm) and a maximum depth of cut of 0.050 inches (1.27 mm), making it suited to fine, controlled grooving passes. It is installed by machinists and toolroom technicians working in production or job-shop environments.

This insert is intended for use on cast iron, non-ferrous metals, and stainless steel workpieces. The positive rake geometry (5-degree rake angle, 3-degree lead angle) reduces cutting forces and helps manage chip flow on materials that can be difficult to machine cleanly. The clamp-style insert holding method provides secure seating during interrupted or continuous cuts. The FLGP2031 insert style and size code make it a direct fit within compatible Flo-Lock toolholders designed for that insert family.

Key Features

• Solid carbide substrate with AC3R grade for toughness and edge retention
• AlTiN PVD coating resists heat and abrasive wear during high-speed grooving
• Left-hand cutting orientation for specific toolholder and approach configurations
• Positive rake angle (5 degrees) reduces cutting forces on cast iron and stainless steel
• Cutting width of 0.031 inches (0.79 mm) with maximum depth of cut of 0.050 inches (1.27 mm)
• Clamp-style insert retention for repeatable, rigid seating

Compatibility

Designed for use with Flo-Lock series toolholders compatible with the FLGP-2031L insert style. Verify toolholder designation and insert pocket dimensions before installation to confirm fit.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down the machine and follow lockout/tagout procedures before changing inserts. Use the correct clamping screw and torque method specified by the toolholder manufacturer to seat the insert properly. Inspect the insert pocket for chips or debris before seating a new insert, as contamination can affect insert position and surface finish.
