Sumitomo 19RB841 Turning Insert TNMG332ENG AC830P Carbide

Product Description

The SUMITOMO 19RB841 is a TNMG-style triangular turning insert manufactured from solid carbide with a CVD coating in grade AC830P. It carries an ANSI code of TNMG332ENG and ISO code TNMG160408N-UG. The insert measures 0.6496 inches in length with a 3/8 inch (0.3750 inch) inscribed circle, a 3/16 inch (0.1875 inch) thickness, and a 1/32 inch (0.0313 inch) corner radius. The neutral hand orientation and 0-degree relief angle (clearance code N, tolerance code M) make it suitable for a range of turning operations. It is installed by machinists and CNC turning center operators working in production and job-shop environments.

This insert is designed for external and internal turning applications where consistent tool life and chip control are priorities. The ENG chip breaker geometry is optimized for medium cutting conditions. Primary workpiece material classifications are M (stainless steel) and P (steel), with universal secondary material applicability. It conforms to ANSI and ISO 13399 standards and falls within material grades C5, C5A, and C6. Typical applications include shaft turning, facing, and profiling operations on CNC lathes and turning centers in both light and medium-duty production settings.

Key Features

• Solid carbide construction with CVD coating in manufacturer grade AC830P for extended wear resistance
• ENG chip breaker geometry engineered for controlled chip formation in medium turning operations
• Triangle insert shape (60-degree included angle) provides three usable cutting edges per insert
• Neutral hand orientation accommodates both conventional and climb cutting setups
• Compliant with ANSI and ISO 13399 standards for consistent toolholder interchangeability
• Clamp and pin insert holding method for secure seating in compatible toolholders

Compatibility

Designed for use in TNMG-style toolholders conforming to ANSI and ISO 13399 specifications. Compatible with toolholder seats accepting a 3/8 inch inscribed circle triangular insert with a 0.1500 inch hole diameter. Suitable for machining steel (P) and stainless steel (M) workpiece materials per ISO material classification.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping torque and seating procedures. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Inspect the toolholder pocket for chips, debris, or wear before seating the insert, as contamination in the pocket affects cutting geometry and surface finish. Always verify insert orientation and hand before resuming cutting operations.
