Sumitomo 19RJ841 Turning Insert TNMG332ENG AC820P Carbide

Product Description

The SUMITOMO 19RJ841 is a solid carbide CVD-coated turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. Conforming to ANSI code TNMG332ENG and ISO code TNMG160408N-UG, this insert features a 60-degree triangular shape with a neutral hand orientation and a negative rake geometry. The AC820P manufacturer grade coating delivers wear resistance suited for medium to finishing cut applications. With a 3/8-inch inscribed circle, a 1/32-inch corner radius, and an overall length of 0.6496 inches, it is installed by machinists and CNC operators working in production and job-shop environments.

This insert is primarily intended for machining steel and a range of ISO P and M workpiece materials, making it a practical choice for both general-purpose turning and applications demanding consistent surface finish and tool life. The ENG chip breaker geometry supports controlled chip formation across a range of depths of cut and feed rates. It is held in place using a clamp and pin insert holding method, compatible with standard TNMG-style toolholders used in production turning setups. Minimum order quantity is 10 pieces; each package contains 1 insert.

Key Features

• Solid carbide substrate with CVD coating for extended wear life on steel and M-class materials
• AC820P grade with ENG chip breaker geometry for controlled chip evacuation
• 60-degree triangle insert shape with negative rake and neutral hand for versatile toolholder compatibility
• 1/32-inch corner radius for finishing and medium turning applications
• Clamp and pin holding method for secure seating in TNMG-style toolholders
• Compliant with ANSI and ISO 13399 standards

Compatibility

Designed for use in TNMG-style toolholders that accept a 3/8-inch inscribed circle, 3/16-inch thick triangular turning insert with a clamp and pin holding method. Compatible with ISO P and M primary workpiece material classifications, with steel noted as a secondary workpiece material.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware to seat the insert securely in the toolholder pocket. Inspect the insert pocket and clamping surfaces for debris or wear before seating a new insert.
