Sandvik Coromant 5725078 Ceramic Turning Insert T-max P

Product Description

The SANDVIK COROMANT 5725078 is a ceramic turning insert designed for high-speed metal removal on difficult-to-machine materials. It carries a Titanium Nitride (TiN) coating and features an 80-degree diamond shape (CNGA style) with a neutral hand orientation. The inscribed circle measures 0.5 inches and the corner radius is 0.0313 inches. With four cutting edges per insert, this indexable tool is well-suited for production turning applications where tool life and surface finish consistency are critical. Licensed machinists, CNC operators, and toolroom technicians install this insert in compatible CNGA-style toolholders.

This insert is engineered primarily for turning cast iron and is also rated for superalloys and titanium as secondary workpiece materials. It belongs to the T-Max P series and is identified by ISO code CNGA 12 04 08T01020 650 with grade designation 650. Typical applications include finish and semi-finish turning on CNC lathes and turning centers in both job shop and production environments. The A-style chip breaker geometry supports controlled chip formation during continuous and light interrupted cuts.

Compatibility

Designed for use in CNGA-style indexable turning toolholders accepting a 0.5-inch inscribed circle insert with clamp and pin holding method. Primary workpiece material compatibility is cast iron (ISO material code K); secondary compatibility includes superalloys and titanium (ISO material code S).

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician with the machine powered down and the spindle locked before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified for the toolholder to secure the insert without over-tightening. Inspect the pocket and seating surfaces for chips or debris before seating a new insert edge. Follow the machine tool manufacturer and toolholder guidelines for proper clamping sequence.
