Sumitomo 19HVANZ Turning Insert CNMG431ESU AC510U Carbide

Product Description

The SUMITOMO 19HVANZ is a solid carbide turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. It carries the ANSI designation CNMG431ESU and ISO code CNMG120404N-SU, placing it in the CN series of indexable inserts. The insert features a PVD-applied dual-layer TiAlN and AlCrN coating marketed under Sumitomo's Super ZX designation, which targets heat resistance and edge toughness at elevated cutting speeds. A positive rake angle of 13 degrees and the ESU chip breaker geometry work together to control chip flow and reduce cutting forces. The neutral hand orientation allows use in both right- and left-hand toolholders. Licensed HVAC mechanics do not install this part — it is specified and installed by machinists and CNC programmers in metalworking environments.

This insert is engineered for turning superalloy workpiece materials, making it relevant to aerospace, energy, and industrial manufacturing operations where nickel-based and titanium alloys are common. The secondary workpiece material code S confirms its suitability for superalloys. The ESU chip breaker geometry is suited for finishing and semi-finishing passes where tight chip control and surface finish consistency are priorities. Toolroom technicians and CNC operators sourcing replacement inserts for CNMG-style toolholders will find this insert fits standard CNMG clamp and pin holding configurations.

Key Features

• Solid carbide substrate with PVD-applied TiAlN and AlCrN dual-layer coating (Super ZX designation) for heat and wear resistance
• ESU chip breaker geometry engineered for positive-rake finishing and semi-finishing of superalloys
• Neutral hand orientation compatible with both right- and left-hand CNMG toolholders
• 80-degree diamond insert shape (Insert Shape Code C) provides two usable cutting edges per insert
• Clamp and pin holding method for secure, repeatable seating in standard CNMG pockets
• Compliant with ANSI and ISO 13399 standards for insert geometry and identification

Compatibility

Designed as a direct-fit replacement for standard CNMG431 toolholder pockets using clamp and pin holding. Compatible with toolholders specified for ANSI CNMG431 inserts and ISO CNMG120404 geometry. Verify toolholder pocket dimensions and chip breaker clearance before installation.

Installation Notes

Insert replacement is performed by qualified machinists or CNC operators with the machine powered down and the spindle locked out per facility lockout/tagout procedures. Use a torque wrench appropriate for the toolholder manufacturer's specified clamp screw torque — do not use the torque value from this listing as none was provided in the product data. Inspect the toolholder pocket and locating pin for wear or debris before seating the new insert. Discard worn inserts according to applicable sharps and carbide-waste disposal procedures.
