Tool-flo 563878LN4C Grooving Insert FLG3178 GP50 Carbide Tin

Product Description

The TOOL-FLO 563878LN4C is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. This left-hand insert carries a GP50 manufacturer grade and features a PVD-applied TiN coating for improved wear resistance and extended tool life. With a cutting width of 0.178 inches (4.52 mm) and a maximum depth of cut of 0.180 inches (4.57 mm), it is sized for controlled, repeatable grooving in ferrous and non-ferrous materials. It belongs to the Flo-Lock series and is installed by machinists and toolroom technicians in production and job-shop environments.

This insert is suited for grooving applications on lathes where left-hand orientation is required, including O-ring groove cutting, snap-ring groove work, and part-off operations. The FLG insert style fits Flo-Lock compatible toolholders designed for the 3/8-inch gage diameter and 3178 insert size designation. It is appropriate for both light and moderate-duty cuts within its rated depth range of 0.150 to 0.200 inches (4.00 to 5.00 mm), making it a practical choice for shops running medium to fine finishing passes on turned components.
