Tool-flo 6335125PRAC3R Grooving Insert Flo-lock AC3

Product Description

The TOOL-FLO 6335125PRAC3R is a solid carbide grooving insert in the Flo-Lock series, designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries an AlTiN coating applied via PVD process, which provides thermal resistance and extended tool life in demanding cuts. The insert features a right-hand orientation, a 0.125 inch cutting width, and a maximum depth of cut of 0.25 inches. Clamp-style holding secures the insert firmly in the toolholder. This insert is sized and specified for use by machinists and toolroom technicians working in production turning environments.

This insert is suited for grooving and parting applications on cast iron, non-ferrous metals, and stainless steel. It performs well in both light and moderate material removal passes within its rated depth range. The neutral rake geometry and chip breaker (CB) configuration help manage chip flow during continuous grooving cuts. The single-end design means each insert provides one cutting edge. Typical applications include groove profiling and face grooving on turned components in job shop and production settings.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine before changing inserts. Seat the insert fully against the insert pocket before tightening the clamp to avoid rocking or misalignment. Inspect the insert seat and clamp for chips or debris that could affect seating accuracy, and confirm toolholder condition meets the manufacturer's requirements for the Flo-Lock clamping system.
