Sumitomo 19RJAFL Turning Insert CNMG543EMU AC820P Carbide

Product Description

The SUMITOMO 19RJAFL is a solid carbide turning insert in the CNMG style, designed for precision metal cutting on CNC lathes and turning centers. It carries the AC820P manufacturer grade with Absotech CVD coating, engineered to handle demanding cutting conditions on steel and stainless steel workpieces. The insert features an 80-degree diamond shape, a neutral hand orientation, and an EMU chip breaker geometry suited for medium to finishing passes. The 3/64-inch corner radius and CNMG543EMU ANSI designation make this a precise, geometry-specific choice for trade machinists and toolroom professionals.

This insert is rated for primary workpiece materials classified under ISO material groups M and P, covering stainless steel and carbon and alloy steels. It is appropriate for use in production turning environments where consistent chip control and tool life are priorities. The EMU chip breaker geometry performs in medium-depth finishing and semi-finishing operations. Material grade compatibility spans C5A, C6, C7, and C8 carbide classifications. The insert is also identified by ISO code CNMG160612N-MU, which assists with cross-referencing in international tooling systems.

Key Features

• AC820P grade with Absotech CVD coating for extended wear resistance on steel and stainless workpieces
• 80-degree diamond insert shape (Shape Code C) for versatile turning and profiling
• EMU chip breaker geometry optimized for medium to finishing cut passes
• Neutral hand orientation for flexible tool holder compatibility
• Clamp and pin holding method for secure seating in CNMG-style tool holders
• Complies with ANSI and ISO 13399 standards for tooling data interoperability

Compatibility

Designed for use in CNMG-style turning tool holders that accept a 5/8-inch inscribed circle insert with a 1/4-inch thickness and 1/4-inch hole diameter. Compatible with tool holders specifying the ANSI code CNMG543EMU or ISO code CNMG160612N-MU. Suited for turning applications on primary workpiece material groups M and P as defined by ISO material classification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Seat the insert fully against the tool holder pocket and tighten the clamp or pin per the tool holder manufacturer specifications. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper insert contact and runout control.
