Sumitomo 19RBCDT Carbide Turning Insert AC830P Cnmg

Product Description

The SUMITOMO 19RBCDT is a CNMG-style carbide turning insert engineered for precision metal cutting on CNC lathes and turning centers. Manufactured to the AC830P grade with a CVD-applied Al2O3 coating, this insert delivers heat resistance and wear performance suited for continuous and interrupted turning operations. The 80-degree diamond shape provides a strong cutting edge geometry with a positive rake angle of 4 degrees, while the EME chip breaker controls chip flow across a range of depths of cut. With an inscribed circle of 0.625 inches and a corner radius of 0.031 inches, this insert is sized for medium-duty finish and semi-finish turning work. Licensed machinists and CNC operators install this insert type.

The 19RBCDT is designed for turning applications across universal secondary workpiece materials, with ISO material codes M and P indicating suitability for stainless steel and carbon and alloy steel stock. The EME chip breaker geometry supports consistent chip evacuation in finish and semi-finish turning scenarios. The neutral hand orientation allows use in standard right-hand and left-hand toolholders that accept CNMG-style inserts. This insert conforms to ANSI and ISO 13399 standards, making it compatible with digital tool management systems used in modern machining environments.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified procedure when clamping the insert. Inspect the insert seat and clamp for debris or damage before installing a new insert to ensure proper seating and edge repeatability.
