Tool-flo 573689RJ5R Grooving Insert GP3 Carbide Tin Flo-lock

Product Description

The TOOL-FLO 573689RJ5R is a solid carbide grooving insert in the Flo-Lock series, designed for precision external grooving and parting operations on CNC lathes and turning centers. Built from micrograin carbide with a PVD-applied TiN coating, it delivers a 4.80 mm cutting width and a maximum depth of cut of 4.57 mm. The right-hand orientation and positive rake angle of 55 degrees support clean chip evacuation and reduced cutting forces. Machinists and tool-and-die professionals install this insert into compatible Flo-Lock toolholders for repeatable, high-accuracy grooving in steel workpiece applications.

This insert is suited for production turning environments where consistent groove geometry is required. With an ISO code of FLGP-3189R and an insert size designation of 3189, it targets grooving depths in the 4.00 mm to 5.00 mm range, making it appropriate for medium-depth grooving passes on steel components. The 3/8 inch gage diameter and a cutting height of 0.3440 inches define the seating geometry within the Flo-Lock toolholder system. A 0.0200 to 0.0250 inch corner radius provides a controlled edge break without a full radius profile.

Key Features

• Micrograin solid carbide substrate for wear resistance in steel grooving applications
• PVD TiN coating for improved surface hardness and tool life
• 4.80 mm cutting width with a maximum depth of cut of 4.57 mm
• Positive rake at 55 degrees supports reduced cutting forces and clean chip flow
• Right-hand cutting orientation, insert style FLGP, size code 3189
• No full radius; corner radius of 0.0200 to 0.0250 inches for controlled edge geometry

Compatibility

Designed for use in the Flo-Lock toolholder system, compatible with holders specified for FLGP-style inserts with a 3/8 inch gage diameter and insert size 3189. Primary workpiece material is steel.

Installation Notes

Installation is performed by machinists or tooling technicians during machine setup with the spindle fully stopped and the machine locked out per shop safety procedures. Seat the insert firmly in the Flo-Lock pocket and confirm secure clamping before running the machine. Inspect the insert seating and clamp screw torque per the toolholder manufacturer specifications. Replace the insert at the first sign of chipping, excessive wear, or dimensional drift in the groove output.
