Sumitomo 19DYBVQ AC700G Carbide Turning Insert CCMT32.52ELU

Product Description

The SUMITOMO 19DYBVQ is a CCMT-style solid carbide turning insert carrying the AC700G grade designation. It features an 80-degree diamond shape with a 3/8-inch inscribed circle, a 1/32-inch corner radius, and a 5/32-inch insert thickness. The TiC coating is applied via CVD process, providing surface hardness suited for interrupted and continuous cutting passes. The ELU chip breaker geometry promotes positive rake cutting action at 12 degrees, controlling chip flow during turning operations. This insert is specified for use on CNC and manual turning centers by machinists and tool-and-die professionals working in production or job-shop environments.

The 19DYBVQ is designed for turning applications on cast iron and steel workpieces. Its positive rake geometry and ELU chip breaker make it well suited for medium finishing cuts where chip control and surface finish consistency are priorities. The screw-holding method is compatible with standard CCMT insert pockets, and the neutral hand orientation allows use in standard right-hand or neutral toolholders. This insert conforms to ANSI code CCMT32.52ELU and ISO code CCMT09T308N-LU, making it interchangeable with holders designed to those standards.

Key Features

• AC700G solid carbide grade with CVD-applied TiC coating for wear resistance on steel and cast iron
• 80-degree diamond insert shape with 1/32-inch corner radius for versatile turning geometry
• ELU chip breaker with 12-degree positive rake angle for controlled chip formation
• Screw-held CCMT pocket style with clearance code C and tolerance code M
• Dual standard compliance: ANSI CCMT32.52ELU and ISO CCMT09T308N-LU
• Neutral hand orientation for use in standard CCMT toolholders

Compatibility

Designed as an OEM-style replacement and standard insert for CCMT-style turning toolholders conforming to ANSI CCMT32.52ELU or ISO CCMT09T308N-LU pocket specifications. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation is performed by a machinist or toolroom technician using the appropriate Torx or hex key for the insert clamping screw as specified by the toolholder manufacturer. Always index or replace inserts with the machine at a full stop and spindle locked. Confirm the insert pocket is free of chips and debris before seating the new insert to ensure proper contact and prevent premature edge failure. Follow the toolholder manufacturer torque specification for the clamping screw.
