Sumitomo 19RBW5P Turning Insert DCMT32.51ENK AC830P Carbide

Product Description

The SUMITOMO 19RBW5P is a solid carbide turning insert with ANSI designation DCMT32.51ENK and manufacturer grade AC830P. It features a CVD-applied aluminum oxide (Al2O3) coating designed for wear resistance and thermal stability in turning operations. The insert has a 55-degree diamond shape with a neutral hand orientation and a positive rake angle of 8 degrees, making it well suited for continuous and light interrupted cuts. The inscribed circle measures 3/8 inch, and the corner radius is 1/64 inch. Licensed machinists and CNC lathe operators install this insert type in indexable toolholders for external turning applications.

This insert is intended for use in indexable turning toolholders that accept the DCMT insert style with screw-type holding. It carries an ISO designation of DCMT11T304N-SK and conforms to ANSI and ISO 13399 standards. The ENK chip breaker geometry suits a universal range of workpiece materials, including steel and stainless steel applications. It is appropriate for both production shop and job shop environments running CNC or manual lathes where consistent dimensional tolerances are required.

Key Features

• Solid carbide substrate with CVD-applied Al2O3 coating for high-temperature wear resistance
• 55-degree diamond insert shape with positive rake for reduced cutting forces
• ENK chip breaker geometry rated for universal secondary workpiece material compatibility
• Screw-type insert holding method for secure, repeatable indexing
• Neutral hand orientation fits standard DCMT-style toolholders
• Conforms to ANSI and ISO 13399 standards for insert interchangeability

Compatibility

Designed for use in indexable toolholders accepting the DCMT insert style with screw-type clamping. Conforms to ANSI designation DCMT32.51ENK and ISO designation DCMT11T304N-SK for toolholder compatibility cross-reference.

Installation Notes

Installation is performed by machining professionals using an appropriate torx or hex key to seat and secure the insert screw to the toolholder specification. Ensure the machine spindle is fully stopped and the toolholder is removed from the turret before indexing or replacing the insert. Do not exceed the toolholder manufacturer's recommended depth of cut or feed rate for this insert geometry. Inspect seating surfaces for chips or debris before securing the insert to maintain proper tool geometry.
