Tool-flo 563694LJ5R Grooving Insert GP3 Left Hand Carbide

Product Description

The TOOL-FLO 563694LJ5R is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Built to the FLG-3094L ISO code and manufactured from micrograin solid carbide, this insert carries a GP3 manufacturer grade with a TiN coating applied via PVD process. The cutting width measures 2.39 mm (0.094 inches) and the maximum depth of cut reaches 4.57 mm (0.18 inches). Left-hand orientation, a positive rake angle of 55 degrees, and a 3-degree lead angle make this insert suited to demanding turning applications where consistent chip control and edge life are critical. Machinists and CNC operators in production and job-shop environments are the primary installers.

The 563694LJ5R belongs to the Flo-Lock series from TOOL-FLO and is intended for external grooving operations on turning machines. The insert fits standard Flo-Lock toolholders accepting the FLG style and 3094 size code. It is suited for both production runs and precision work where tight groove tolerances are required. The 3/8-inch gage diameter and 3/32-inch cutting width make this insert appropriate for small-to-medium groove profiles in ferrous and non-ferrous materials where a TiN-coated micrograin carbide grade performs reliably.

Key Features

Compatibility

Designed for use with Flo-Lock series toolholders accepting FLG style inserts in size code 3094. ISO code FLG-3094L identifies the correct holder pairing. Verify toolholder hand and pocket dimensions before installation.

Installation Notes

This insert is installed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate insert seating tool or torx key as specified by the toolholder manufacturer to secure the insert at the correct clamping force - do not over-torque the clamp screw. Confirm left-hand orientation matches the toolholder pocket before seating, and inspect the pocket for chips or debris that could affect seating accuracy.
