Tool-flo 64251J5R Profiling Insert FLPR51 GP3 Carbide

Product Description

The TOOL-FLO 64251J5R is a solid carbide profiling insert in the FLPR series, designed for precision turning and profiling operations on CNC and manual lathes. Built from micrograin carbide with a GP3R manufacturer grade and a TiN PVD coating, this insert delivers consistent edge life on non-ferrous metals and superalloys. The parallelogram shape provides a 55-degree included angle with a positive 10-degree rake angle and an 8-degree relief angle, optimizing chip flow and reducing cutting forces. At 0.125 inches thick with a 0.015-inch corner radius, this insert is suited to fine-tolerance profiling passes where edge geometry must stay repeatable.

This insert is intended for use in profiling and external turning applications, particularly on non-ferrous metals such as aluminum, copper alloys, and brass, as well as superalloy workpieces. It is used in production and job-shop environments by machinists and CNC operators running toolholders compatible with the FLPR-51 insert seat. The right-hand cutting orientation and clamp-and-pin holding method make it a standard fit for TOOL-FLO FLPR-series toolholders. With two cutting edges per insert, it extends useful life before requiring replacement.

Key Features

• Micrograin solid carbide substrate with GP3R grade for consistent edge integrity on non-ferrous metals and superalloys
• TiN PVD coating improves surface finish and edge wear resistance
• Positive rake geometry (10-degree rake angle) reduces cutting forces and heat generation
• 0.015-inch corner radius supports fine-tolerance profiling and contour turning
• Two cutting edges per insert for extended tool life before discard
• Clamp and pin holding method provides secure seating in FLPR-series toolholders

Compatibility

Designed for use in TOOL-FLO FLPR-series toolholders accepting FLPR-51 insert seats. Right-hand cutting orientation. Meets FLPR-51 GP3R standards as specified by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine before seating or removing inserts. Confirm the insert pocket and clamp pin are free of chips and debris before seating to ensure proper contact and prevent premature edge failure. Torque the clamp screw according to the toolholder manufacturer specifications for the FLPR series.
