Tool-flo 64151N4C Profiling Insert FLPL51 GP50 Carbide

Product Description

The TOOL-FLO 64151N4C is a solid carbide profiling and turning insert designed for precision metal removal on steel workpieces. This parallelogram-shaped insert carries the FLPL-51 GP50C designation, features a positive rake geometry with a 10-degree rake angle and an 8-degree relief angle, and is coated with TiN via PVD process for extended cutting edge life. At 0.125 inches thick with a 0.015-inch corner radius and a 55-degree included angle, it delivers controlled chip formation in profile turning and general turning applications. Clamp and pin holding methods are supported. Intended for installation by machining professionals on CNC and manual turning equipment.

This insert is suited for profiling and turning operations on steel in both production and job-shop environments. The left-hand configuration, two cutting edges, and positive rake design make it appropriate for finishing and light to moderate roughing passes where accurate profile geometry is required. A common chipbreaker geometry broadens its range across typical turning scenarios. The 0.361-inch maximum depth of cut supports moderate material engagement without excessive tool pressure.

Compatibility

Designed for use in FLPL series toolholders requiring a size 51 insert. Compatible holding methods include clamp and pin styles. Primary workpiece material is steel. Conforms to standard FLPL-51 GP50C specifications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Verify the toolholder pocket and seating surfaces are clean and free of chips before clamping. Confirm correct left-hand orientation before engaging a cut, as reversing hand orientation can result in tool failure or workpiece damage.
