Tool-flo 64251N4C Profiling Insert FLPR51 GP50 Carbide

Product Description

The TOOL-FLO 64251N4C is a solid carbide profiling and turning insert in the FLPR series, designed for precision metal removal on steel workpieces. This parallelogram-shaped insert carries a GP50 manufacturer grade with a PVD-applied TiN coating, a positive rake geometry at 10 degrees, and a 0.015 inch corner radius for controlled edge engagement. With two cutting edges and an 8-degree relief angle, the insert is engineered for consistent, repeatable performance in profiling and turning operations. Licensed HVAC techs and machinists running CNC lathes or manual turning centers install and index this insert as part of routine tooling maintenance.

This insert is suited for profiling and turning applications on steel in both production and job-shop environments. The right-hand cutting orientation and clamp or pin holding method make it compatible with standard FLPR-series toolholders. A maximum depth of cut of 0.361 inches and an inscribed circle of 0.25 inches support a wide range of pass depths on conventional turning setups. The FLPR51 GP50 designation corresponds to the FLPR-51 GP50C standard.

Key Features

• Solid carbide construction with PVD TiN coating for wear resistance on steel
• Positive rake angle of 10 degrees reduces cutting forces
• 0.015 inch corner radius for fine-detail profiling passes
• Two cutting edges extend usable insert life before replacement
• Right-hand, parallelogram shape with 55-degree included angle for profiling geometry
• Compatible with clamp and pin holding methods for secure seating

Compatibility

Designed for use with FLPR-series toolholders accepting FLPR-51 style inserts. Primary workpiece material is steel. Insert conforms to the FLPR-51 GP50C standard.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Disengage the machine spindle and confirm all moving parts are fully stopped before indexing or replacing the insert. Use the appropriate torque wrench or clamping hardware specified for the FLPR-series toolholder to secure the insert without over-tightening the clamp screw. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and alignment.
