Tool-flo C5125000N4E Grooving Insert TNMA54 GP50 Solid Carbide

Product Description

The TOOL-FLO C5125000N4E is a solid carbide grooving insert in the TNMA54 style, designed for on-edge grooving operations on CNC lathes and turning centers. Manufactured to GP50 grade and finished with a PVD-applied TiN coating, this insert delivers consistent cutting performance in a neutral hand orientation. The cutting width is 0.25 inches with a maximum depth of cut reaching 0.275 inches. Screw-style holding secures the insert rigidly in compatible toolholders. Machinists and CNC operators in production and job-shop environments rely on this style of insert for repetitive grooving, parting, and profile work across a range of workpiece materials.

This insert is suited for external and internal grooving applications on turning equipment where on-edge insert geometry is specified. The neutral hand configuration makes it adaptable to both right- and left-hand toolholder setups depending on the application. Typical use cases include groove cutting in ferrous metals and other materials where a GP50 carbide grade and TiN coating provide adequate wear resistance and surface finish. It is sold individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction with PVD TiN coating for extended wear life
• GP50 manufacturer grade suited for general-purpose grooving applications
• 0.25 inch cutting width with maximum depth of cut of 0.275 inches
• Neutral hand orientation for flexible toolholder compatibility
• Screw holding method ensures secure, repeatable insert positioning

Compatibility

Designed as an OEM-style replacement or direct-fit grooving insert for toolholders accepting TNMA54-style on-edge inserts with screw-style clamping. Verify inscribed circle and thickness dimensions against your toolholder specification before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Use the appropriate torx or hex key to torque the clamping screw to the toolholder specification - do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket and seating surface for chips or debris before seating the new insert.
