Tool-flo 563825PRA3 Grooving Insert C3 Carbide Flo-lock

Product Description

The TOOL-FLO 563825PRA3 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the FLG-3125R-CB ISO designation, this right-hand insert features a 0.125-inch (3.18 mm) cutting width and a maximum depth of cut of 0.180 inch (4.57 mm). Manufactured in micrograin carbide at grade C3 with a bright uncoated finish, it delivers consistent edge sharpness and dimensional control in light to medium grooving applications. The P-style chip breaker promotes chip evacuation and reduces cutting forces during interrupted or continuous grooves.

This insert is suited for use in ferrous turning applications where a C3-grade uncoated carbide performs reliably, including finish grooving of steel and cast iron at moderate cutting speeds. It seats in a clamp-style holder and belongs to TOOL-FLO's Flo-Lock series, a system designed for repeatable insert indexing without the need for special seating tools. Typical users include CNC machinists, tool-and-die shops, and precision parts manufacturers running production or job-shop turning operations.

Installation Notes

Installation is performed by CNC machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully into the clamp pocket and confirm the chip breaker orientation matches the intended cut direction before resuming operation. Inspect the clamp and pocket for chips or debris that could prevent proper seating and affect dimensional accuracy.
