Ingersoll Cutting Tools 5522325 Turning Insert CNMG433RGP

Product Description

The INGERSOLL CUTTING TOOLS 5522325 is a CNMG-style solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Carrying the TT8125B manufacturer grade, this insert features a multilayer CVD coating of TiCN, Al2O3, and TiN that provides wear resistance and thermal protection during aggressive steel turning operations. The diamond-shaped insert body has a negative rake geometry and an 80-degree included angle, delivering strong cutting-edge support at the tool tip. With four usable cutting edges, the insert maximizes tool life per unit cost. It is sized at a 0.5000-inch inscribed circle with a 0.0470-inch corner radius and is held in place by a clamp-style toolholder. Licensed machinists and CNC operators install and index this insert as part of routine tool-change procedures in production or job-shop environments.

This insert is intended for turning applications where the primary workpiece material is steel, matching the P-grade workpiece material classification. The RGP chip breaker geometry manages chip flow during continuous and interrupted steel cuts at moderate-to-high feed rates. It is suited for external and internal turning operations where a neutral-hand insert orientation is required. The ANSI designation for this insert is CNMG433RGPTT8125B and the ISO designation is CNMG120412RGP TT8125B, allowing cross-reference with toolholder catalogs and compatible pocket specifications.

Key Features

• Solid carbide substrate with multilayer CVD coating: TiCN, Al2O3, TiN for extended tool life in steel cutting
• Four cutting edges per insert, reducing cost-per-edge in high-volume turning operations
• RGP chip breaker geometry designed to control chip formation during steel turning at varied feed rates
• 0.0470-inch corner radius balances surface finish quality with cutting-edge strength
• Negative rake, 80-degree diamond shape (CNMG insert style) provides robust edge support and predictable breakout resistance
• Clamp-held seating method ensures secure insert positioning and repeatable edge indexing

Compatibility

This insert conforms to ANSI designation CNMG433RGPTT8125B and ISO designation CNMG120412RGP TT8125B. It is designed to seat in CNMG-style clamp toolholders with a size-433 pocket specification and a 0.5000-inch inscribed circle. Confirm toolholder pocket geometry and clamp style before indexing.

Installation Notes

Indexing and replacement of turning inserts is performed by qualified CNC machinists or toolroom technicians. The machine spindle must be stopped and the turret must be in a safe, locked position before removing or seating any insert. Use the appropriate torque wrench per the toolholder manufacturer's clamping screw specification, and inspect the pocket seat for chips or debris before seating the new insert. Follow the toolholder manufacturer's indexing procedure to ensure full seating and accurate edge positioning before resuming cuts.
