Sumitomo 19HVAFL Turning Insert CNMG543EMU AC510U Carbide

Product Description

The SUMITOMO 19HVAFL is a solid carbide turning insert in the CNMG543EMU geometry, coated with TiAlN and AlCrN via a PVD process under Sumitomo's proprietary Super ZX coating designation. It features an 80-degree diamond shape, a neutral hand orientation, and a positive rake angle of 4 degrees. The AC510U grade and dual-layer PVD coating are engineered to resist heat and wear during high-speed cutting operations. Machining professionals and CNC lathe operators install this insert in compatible toolholders for precision turning applications where thermal stability and edge retention are critical.

This insert is suited for turning operations targeting superalloys, making it a fit for aerospace, power generation, and industrial machining environments where difficult-to-machine materials are common. The EMU chip breaker geometry is designed to manage chip flow in these demanding cutting conditions. The insert mounts using a clamp and pin holding method standard to CNMG-style toolholders, and it conforms to both ANSI and ISO 13399 standards, ensuring broad toolholder compatibility across setups that accept the CNMG format.

Key Features

• AC510U grade with TiAlN and AlCrN PVD coating (Super ZX) for high heat and wear resistance
• 80-degree diamond insert shape with neutral hand orientation
• EMU chip breaker geometry optimized for superalloy turning
• Positive rake angle of 4 degrees for reduced cutting forces
• Clamp and pin holding method compatible with standard CNMG toolholders
• Conforms to ANSI and ISO 13399 standards; ISO code CNMG160612N-MU

Compatibility

Designed for use in toolholders accepting CNMG-style inserts with a clamp and pin holding method. ANSI code CNMG543EMU and ISO code CNMG160612N-MU identify the exact geometry for cross-referencing compatible toolholder systems.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and de-energize the machine before changing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to seat the insert correctly - do not overtighten or hand-tighten with substitute hardware. Inspect the insert seat and clamp for wear or contamination before each insert change to maintain accurate tool geometry.
