Sandvik Coromant 5915127 WNMG432-SM 1115 Turning Insert

Product Description

The SANDVIK COROMANT 5915127 is a solid carbide turning insert in the WNMG432-SM style, designed for precision external turning operations on CNC lathes and turning centers. It carries a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, delivering heat resistance and edge stability at elevated cutting speeds. The insert features an 80-degree trigon shape with a neutral hand orientation, a 0.5-inch inscribed circle, and a corner radius of 0.0313 inches. With six cutting edges per insert, it offers extended tool life and favorable cost-per-edge economics for production turning applications. Machinists and CNC operators install this insert into compatible WNMG-style toolholders.

This insert is engineered primarily for turning stainless steel, with secondary suitability for superalloys and titanium. It belongs to the SANDVIK COROMANT T-Max P series, which targets ISO material group M and S workpiece materials in both roughing and semi-finishing passes. The SM chip breaker geometry is optimized for stable chip control in these demanding materials, making it appropriate for aerospace, medical, and industrial component machining where surface integrity and dimensional accuracy are critical. It is sold individually with a minimum order quantity of 10.

Installation Notes

Installation is performed by CNC machinists and turning center operators. Ensure the machine spindle is stopped and all axes are at a safe position before indexing or replacing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified procedure when seating the clamp or pin. Inspect the insert pocket for chips or debris before seating a new insert to ensure full, flush contact.
