Sumitomo 19RBWBW Turning Insert TNMG548ENZ AC830P Carbide

Product Description

The SUMITOMO 19RBWBW is a TNMG-style indexable turning insert manufactured from solid carbide and finished with an Al2O3 (aluminum oxide) coating applied via CVD process. Carrying the manufacturer grade designation AC830P, this insert is designed for external turning operations on CNC and manual lathes. The triangular insert geometry features a 60-degree included angle, a 5/8-inch inscribed circle, and a 1/8-inch corner radius. The ENZ chip breaker geometry promotes controlled chip evacuation across a range of workpiece materials. Installation and replacement are handled by licensed machinists and CNC operators in production and job-shop environments.

The 19RBWBW is rated for universal secondary workpiece material applications, covering material codes M and P, which correspond to stainless steels and carbon and alloy steels respectively. With a neutral hand orientation, the insert suits straight turning and facing operations without requiring a handed toolholder. The TNMG548ENZ ANSI designation and ISO code TNMG270632N-UZ allow cross-referencing with standard toolholder catalogs. This insert fits toolholders designed for the TN series and is appropriate for medium to finish turning passes in steel and stainless applications.

Key Features

• Solid carbide substrate with CVD-applied Al2O3 coating for thermal and abrasion resistance
• AC830P manufacturer grade suited for steel and stainless steel turning
• ENZ chip breaker geometry for reliable chip control during continuous cutting
• Neutral hand orientation compatible with standard TNMG toolholders
• 60-degree triangular insert shape provides three usable cutting edges per insert
• Clamp and pin holding method for secure seating under cutting loads

Compatibility

Designed for use in TNMG-style indexable toolholders within the SUMITOMO TN series. ANSI code TNMG548ENZ and ISO code TNMG270632N-UZ allow direct cross-referencing with compatible toolholder catalogs. Rated for secondary workpiece material codes M and P.

Installation Notes

Installation is performed by qualified machinists following standard indexable insert procedures. Power down and lock out the machine spindle before indexing or replacing any cutting insert. Use the appropriate torx or clamp screw driver specified by the toolholder manufacturer to secure the clamp and pin holding system. Inspect the toolholder pocket and seating surfaces for wear or contamination before seating the new insert.
