Tool-flo 573625RJ5R Grooving Insert GP3 Solid Carbide Tin

Product Description

The TOOL-FLO 573625RJ5R is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured from micrograin carbide stock and finished with a PVD-applied TiN coating, this right-hand insert delivers a 0.1252 inch (3.18 mm) cutting width and a maximum depth of cut of 0.1799 inch (4.57 mm). The GP3 grade and positive rake geometry are optimized for steel workpiece materials, reducing cutting forces and improving surface finish in high-volume production environments. Machinists and tool-and-die professionals rely on this insert for repeatable, tight-tolerance groove profiles.

This insert belongs to the Flo-Lock series and is suited for external grooving applications in both production shops and job shops running steel components. The FLGP style with insert size code 3125 seats into compatible Flo-Lock toolholders designed for that insert family. The 3/8 inch (0.3750 inch) gage diameter and a cutting height of 0.3440 inch make it appropriate for medium-duty turning work where consistent groove width and depth control are required. Primary workpiece material is steel.

Key Features

• Solid micrograin carbide substrate for wear resistance in steel grooving applications
• PVD TiN coating reduces friction and extends tool life at the cutting edge
• Positive rake angle (55 degrees) minimizes cutting forces and heat generation
• Right-hand cut orientation with a 3-degree lead angle for controlled chip flow
• Corner radius range of 0.0050 to 0.0100 inch provides a slight edge prep without a full radius profile
• Maximum depth of cut range of 0.1500 to 0.2000 inch supports a consistent grooving envelope

Compatibility

Designed for use in Flo-Lock series toolholders accepting the FLGP-3125 insert style. ISO code FLGP-3125R. Also cross-referenced under MSC/Manufacturer Number FLGP-3125R/L. Verify toolholder seat geometry and clamping mechanism compatibility before installation.

Installation Notes

Installation is performed by a machinist or toolroom technician with the machine in a locked-out, zero-energy state before any insert change. Seat the insert fully into the Flo-Lock pocket and confirm the clamping screw torque per the toolholder manufacturer specification. Inspect the insert seat for chips or debris that could affect seating and runout. Do not exceed the stated maximum depth of cut of 0.1799 inch per pass.
