Sumitomo 196CBPC Turning Insert CCMT21.51ESU AC6030M Carbide

Product Description

The SUMITOMO 196CBPC is a solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to ANSI code CCMT21.51ESU and ISO code CCMT060204N-SU, this insert features an 80-degree diamond shape with a positive rake geometry and a 7-degree relief angle. The AC6030M grade uses a CVD coating process to deliver wear resistance and thermal stability during continuous and interrupted cutting operations. It is installed by machinists and CNC operators in production and job shop environments where consistent tool life and surface finish are required.

This insert is engineered for primary use on stainless steel workpiece materials, corresponding to ISO material code M. It fits into standard CCMT-style toolholders using a screw-holding method. The ESU chip breaker geometry is suited for light-to-medium turning passes where chip control and surface integrity are critical. Typical applications include turning stainless steel shafts, flanges, and similar components in aerospace, industrial, and process equipment manufacturing environments.

Key Features

• AC6030M grade with CVD coating for extended tool life on stainless steel
• 80-degree diamond insert shape (Shape Code C) for versatile approach angles
• ESU chip breaker geometry optimized for light-to-medium turning with positive rake
• Screw-holding method compatible with standard CCMT toolholders
• Meets ANSI and ISO 13399 standards for dimensional consistency
• Neutral hand orientation for flexible use in right- or left-hand setups

Compatibility

Designed for use in CCMT-style screw-clamp turning toolholders accepting a 1/4-inch inscribed circle insert. Conforms to ANSI code CCMT21.51ESU and ISO code CCMT060204N-SU for cross-reference fitment.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturers specified torque — do not overtighten, as this can fracture the carbide. Inspect the toolholder pocket and contact surfaces for chips or burrs before installing a new insert.
