Tool-flo 574625RN4C Grooving Insert GP50 Solid Carbide

Product Description

The TOOL-FLO 574625RN4C is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to GP50 grade with a PVD-applied TiN coating, this right-hand insert delivers consistent performance across a cutting width of 0.1252 inches (3.18 mm) and a maximum depth of cut of 0.2500 inches (6.35 mm). The Flo-Lock series geometry features a positive rake angle of 55 degrees, promoting efficient chip evacuation and reduced cutting forces. Machinists and tooling specialists working with C5 and C6 material grades will find this insert well-suited to high-accuracy grooving applications.

This insert is intended for use in Flo-Lock series toolholders and grooving systems on production turning equipment. It is appropriate for both job-shop and high-volume manufacturing environments where repeatable groove dimensions are critical. The FLGP4125 insert style with a 3/8-inch gage diameter fits standard Flo-Lock tooling blocks used in ferrous and non-ferrous turning applications. The right-hand orientation suits conventional lathe setups where the tool approaches the workpiece from the operator side.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle locked before seating the insert. Confirm the insert is fully seated in the Flo-Lock pocket and that the clamping mechanism engages correctly before resuming operation. Inspect the insert seat and clamping surfaces for chips or debris that could affect seating accuracy. Follow the toolholder manufacturer torque and clamping specifications for proper insert retention.
