Tool-flo 563842LN4C Grooving Insert GP50 Solid Carbide

Product Description

The TOOL-FLO 563842LN4C 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 features a TiN coating applied via PVD process, offering improved surface hardness and wear resistance. It carries a manufacturer grade of GP50 and material grades C5 and C6, making it suitable for a range of ferrous and non-ferrous turning applications. The cutting width is 0.1421 inches (3.61 mm) with a maximum depth of cut of 0.1799 inches (4.57 mm). Machinists and toolroom technicians install this insert into compatible Flo-Lock toolholders for consistent, repeatable groove geometry.

This insert is suited for use in production turning environments where controlled groove width and depth are critical. The left-hand orientation makes it appropriate for specific approach directions in grooving or face grooving setups. The FLG insert style, combined with a 3-degree lead angle and 55-degree rake angle, is intended for applications requiring clean groove walls and predictable chip control. It is a single-use, non-multi-use insert not designed for repositioning or re-indexing beyond its intended cutting edge.

Installation Notes

Installation of grooving inserts should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per OSHA lockout/tagout procedures. Seat the insert fully and evenly in the pocket before tightening the clamping screw to the toolholder specification. Inspect the insert pocket and clamping components for wear or debris before each installation. Do not use a damaged or improperly seated insert, as this can cause insert fracture or workpiece damage.
