Sumitomo 19RJ696 Carbide Turning Insert Snmm AC820P

Product Description

The SUMITOMO 19RJ696 is a SNMM-style square carbide turning insert engineered for general and heavy-duty external turning operations. Manufactured in grade AC820P with a CVD-applied aluminum oxide (Al2O3) coating, this insert delivers wear resistance and thermal stability when machining steel workpieces at production rates. The insert features a neutral rake angle, a 1 inch inscribed circle, and a 0.375 inch thickness. The EHP chip breaker geometry controls chip flow during continuous and semi-interrupted cuts. Machinists and CNC lathe operators install this insert in compatible SNMM toolholders as part of a clamp and pin holding system.

The 19RJ696 is suited for turning steel (ISO P workpiece material) in both roughing and finishing passes where consistent chip control and edge integrity are required. The square insert shape provides four usable cutting edges per insert, making it an efficient choice for high-volume turning cells in manufacturing and job shop environments. The neutral hand designation makes it compatible with both right- and left-hand tool setups depending on the holder configuration used.

Key Features

• AC820P CVD-coated carbide grade with Al2O3 finish for thermal and wear resistance
• SNMM insert style with square shape and 90-degree included angle - four usable cutting edges
• 1 inch inscribed circle and 1 inch insert length for robust depth-of-cut capability
• 3/32 inch (0.0938 inch) corner radius for controlled surface finish on steel
• EHP chip breaker geometry designed for effective chip control in steel turning
• Neutral rake and neutral hand - compatible with standard SNMM clamp and pin toolholders

Compatibility

Designed for use in SNMM-style toolholders utilizing a clamp and pin holding method. Conforms to ANSI and ISO 13399 standards. ISO code SNMM250924N-HP. Intended for turning applications on steel workpieces (ISO P material group).

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and all motion is locked out before indexing or replacing inserts. Seat the insert fully against the pocket locating surfaces before tightening the clamp to avoid micro-movement under cutting load. Inspect the clamp, pin, and pocket for wear or debris before installing a new insert.
