Sumitomo 19DYBPY Carbide Turning Insert AC700G Tic

Product Description

The SUMITOMO 19DYBPY is a DCMT-style solid carbide turning insert engineered for precision metal cutting in CNC and manual turning applications. Manufactured to ANSI and ISO 13399 standards, this insert carries the AC700G grade designation and a CVD-applied TiC coating for extended wear resistance. The 55-degree diamond shape delivers a sharp, geometry-optimized cutting profile, while the EMU chip breaker controls chip flow in interrupted and continuous cuts. With a neutral rake angle and a 7-degree relief angle, the insert is well-suited for stable, low-vibration turning passes on cast iron and steel workpieces.

This insert is intended for use in external turning operations on ferrous materials, primarily cast iron and steel. It fits standard DCMT-style toolholders that use a screw-type insert holding method, making it compatible with a wide range of OEM and aftermarket turning tool bodies used in production and job-shop environments. Licensed machinists and CNC operators working in general manufacturing, maintenance machining, or toolroom applications will find this insert appropriate for medium-duty turning passes where surface finish and dimensional consistency are priorities.

Key Features

• AC700G carbide grade with CVD TiC coating for wear resistance on cast iron and steel
• 55-degree diamond insert shape (Shape Code D) for versatile profiling and turning
• EMU chip breaker geometry for controlled chip evacuation
• Neutral rake and 7-degree relief angle for stable cutting dynamics
• Screw-type holding method for secure, repeatable seating in DCMT toolholders
• Manufactured to ANSI and ISO 13399 standards for dimensional interchangeability

Compatibility

Designed as a drop-in replacement for DCMT32.52EMU (ANSI) and DCMT11T308N-MU (ISO) style inserts. Fits screw-clamp DCMT toolholders requiring a 3/8-inch inscribed circle insert. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation is performed by licensed machinists or CNC operators. Power down and lock out the machine before seating or replacing any cutting insert. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer's specification - do not overtighten, as this can fracture the carbide. Inspect the insert pocket and clamping screw for damage before installing a new insert.
