Tool-flo 573494LJ5R GP3 Grooving Insert Left Hand Flo-lock

Product Description

The TOOL-FLO 573494LJ5R is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. This left-hand insert belongs to the Flo-Lock series and carries a GP3 manufacturer grade with a TiN coating applied via PVD process. It delivers a cutting width of 2.39 mm (0.0941 inches) and a maximum depth of cut of 4.57 mm (0.1799 inches). The micrograin carbide substrate and positive rake geometry make it well suited for controlled chip formation in steel workpieces. Machinists and CNC operators install this insert as a direct drop-in for compatible Flo-Lock toolholders.

This insert is intended for grooving operations where left-hand cutting orientation is required. Primary workpiece material is steel. The Flo-Lock series is a standard tooling platform used in production turning environments, both in job shop and high-volume manufacturing settings. The 3/8 inch (0.3750 inch) gage diameter and FLGP-3094L ISO code define its seating and indexing geometry within the toolholder system. A lead angle of 3 degrees and a rake angle of 55 degrees contribute to stable cutting performance across typical groove depth ranges of 4.00 mm to 5.00 mm.

Key Features

• Solid carbide construction with micrograin substrate for edge integrity and wear resistance
• TiN coating via PVD process for improved surface hardness and heat resistance
• Left-hand insert orientation for dedicated left-hand grooving setups
• Positive rake angle (55 degrees) for reduced cutting forces on steel workpieces
• Cutting width of 2.39 mm (0.0941 inches) with max depth of cut of 4.57 mm (0.1799 inches)
• Corner radius range of 0.0050 to 0.0100 inches for controlled groove edge geometry

Compatibility

Designed for use with Flo-Lock series toolholders accepting the FLGP-3094L ISO insert style in left-hand orientation with a 3/8 inch gage diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine powered down and the spindle locked before insert seating. Ensure the toolholder pocket and clamping surfaces are clean and free of chips or debris before inserting. Use the appropriate torque tool per the toolholder manufacturer's clamping specifications. Verify insert orientation and engagement before resuming machine operation.
